Release Notes - Mesos - Version 1.2.0 (WIP)
-------------------------------------------
Additional API Changes:
* [MESOS-6675] - Changed the allocator API to support adding inactive
frameworks. Custom allocator implementations will need to be updated.
* [MESOS-6419] - When a framework re-registers after master failover,
it is only allowed to change certain fields in its FrameworkInfo.
For example, changing "failover_timeout" is allowed, but changing
"role" is not. In previous Mesos releases, the same restrictions on
changes to FrameworkInfo were only enforced after framework
failover, not master failover.
* [MESOS-6286] - If an agent restarts but fails to complete recovery
within `agent_reregister_timeout`, the master will now mark the
agent as unreachable. This mainly changes behavior in two
situations: (a) the master will now be more robust if agent recovery
hangs indefinitely (e.g., due to a container being in a bad state),
and (b) if agent recovery takes a very long time (e.g., because the
agent's work directory contains a large number of completed tasks),
the master might now mark an agent unreachable that would previously
have been able to eventually recover successfully.
Release Notes - Mesos - Version 1.1.1 (WIP)
-------------------------------------------
* This is a bug fix release.
All Issues:
** Bug
* [MESOS-6002] - The whiteout file cannot be removed correctly using aufs backend.
* [MESOS-6142] - Frameworks may RESERVE for an arbitrary role.
* [MESOS-6360] - The handling of whiteout files in provisioner is not correct.
* [MESOS-6411] - Add documentation for CNI port-mapper plugin.
* [MESOS-6526] - `mesos-containerizer launch --environment` exposes executor env vars in `ps`.
* [MESOS-6571] - Add "--task" flag to mesos-execute.
* [MESOS-6597] - Include v1 Operator API protos in generated JAR and python packages.
* [MESOS-6621] - SSL downgrade path will CHECK-fail when using both temporary and persistent sockets.
* [MESOS-6676] - Always re-link with scheduler during re-registration.
* [MESOS-6848] - The default executor does not exit if a single task pod fails.
* [MESOS-6852] - Nested container's launch command is not set correctly in docker/runtime isolator.
* [MESOS-6917] - Segfault when the executor sets an invalid UUID when sending a status update.
Release Notes - Mesos - Version 1.1.0
-------------------------------------
This release contains the following new features:
* [MESOS-2449] - **Experimental** support for launching a group of tasks
via a new `LAUNCH_GROUP` Offer operation. Mesos will guarantee that either
all tasks or none of the tasks in the group are delivered to the executor.
Executors receive the task group via a new `LAUNCH_GROUP` event.
* [MESOS-2533] - **Experimental** support for HTTP and HTTPS health checks.
Executors may now use the updated `HealthCheck` protobuf to implement
HTTP(S) health checks. Both default executors (command and docker) leverage
`curl` binary for sending HTTP(S) requests and connect to `127.0.0.1`,
hence a task must listen on all interfaces. On Linux, for BRIDGE and USER
modes, docker executor enters the task's network namespace.
* [MESOS-3421] - **Experimental** Support sharing of resources across
containers. Currently persistent volumes are the only resources allowed to
be shared.
* [MESOS-3567] - **Experimental** support for TCP health checks. Executors
may now use the updated `HealthCheck` protobuf to implement TCP health
checks. Both default executors (command and docker) connect to `127.0.0.1`,
hence a task must listen on all interfaces. On Linux, for BRIDGE and USER
modes, docker executor enters the task's network namespace.
* [MESOS-4324] - Allow tasks to access persistent volumes in either a
read-only or read-write manner. Using a volume in read-only mode can
simplify sharing that volume between multiple tasks on the same agent.
* [MESOS-5275] - **Experimental** support for linux capabilities. Frameworks
or operators now have fine-grained control over the capabilities that a
container may have. This allows a container to run as root, but not have all
the privileges associated with the root user (e.g., CAP_SYS_ADMIN).
* [MESOS-5344] - **Experimental** support for partition-aware Mesos
frameworks. In previous Mesos releases, when an agent is partitioned from
the master and then reregisters with the cluster, all tasks running on the
agent are terminated and the agent is shutdown. In Mesos 1.1, partitioned
agents will no longer be shutdown when they reregister with the master. By
default, tasks running on such agents will still be killed (for backward
compatibility); however, frameworks can opt-in to the new PARTITION_AWARE
capability. If they do this, their tasks will not be killed when a partition
is healed. This allows frameworks to define their own policies for how to
handle partitioned tasks. Enabling the PARTITION_AWARE capability also
introduces a new set of task states: TASK_UNREACHABLE, TASK_DROPPED,
TASK_GONE, TASK_GONE_BY_OPERATOR, and TASK_UNKNOWN. These new states are
intended to eventually replace the TASK_LOST state.
* [MESOS-5788] - **Experimental** support for Java scheduler adapter. This
adapter allows framework developers to toggle between the old/new API
(driver/scheduler library) implementations, thereby allowing them to easily
transition their frameworks to the new v1 Scheduler API.
* [MESOS-6014] - **Experimental** A new port-mapper CNI plugin, the
`mesos-cni-port-mapper` has been introduced. For Mesos containers, with the
CNI port-mapper plugin, users can now expose container ports through host
ports using DNAT. This is especially useful when Mesos containers are
attached to isolated CNI networks such as private bridge networks, and the
services running in the container needs to be exposed outside these
isolated networks.
* [MESOS-6077] - **Experimental** A new default executor is introduced which
frameworks can use to launch task groups as nested containers. All the
nested containers share resources likes cpu, memory, network and volumes.
Deprecations:
* The following metrics are deprecated and will be removed in Mesos 1.4:
master/slave_shutdowns_scheduled,
master/slave_shutdowns_canceled,
slave_shutdowns_completed.
As of Mesos 1.1.0, these metrics will always be zero. The following new
metrics have been introduced as replacements:
master/slave_unreachable_scheduled,
master/slave_unreachable_canceled,
master/slave_unreachable_completed.
* [MESOS-5955] - Health check binary "mesos-health-check" is removed.
* [MESOS-6371] - Remove the 'recover()' interface in 'ContainerLogger'.
Additional API Changes:
* [MESOS-6204] - A new agent flag called `--runtime_dir`. Unlike
`--work_dir` which persists data across reboots, `--runtime_dir` is designed
to checkpoint state that should persist across agent restarts, but not
across reboots. By default this flag is set to `/var/run/mesos` when run as
root and `os::temp/mesos/runtime/` when run as non-root.
* [MESOS-6220] - HTTP handler failures should result in 500 rather than
503 responses. This means that when using the master or agent endpoints,
failures will now result in a `500 Internal Server Error` rather than a
`503 Service Unavailable`.
* [MESOS-6241] - New API calls (LAUNCH_NESTED_CONTAINER,
KILL_NESTED_CONTAINER and WAIT_NESTED_CONTAINER) have been added to the
v1 Agent API to manage nested containers within an executor container.
Unresolved Critical Issues:
* [MESOS-3794] - Master should not store arbitrarily sized data in ExecutorInfo.
* [MESOS-4642] - Mesos Agent Json API can dump binary data from log files out as invalid JSON.
* [MESOS-5396] - After failover, master does not remove agents with same UPID.
* [MESOS-5856] - Logrotate ContainerLogger module does not rotate logs when run as root with `--switch_user`.
* [MESOS-6142] - Frameworks may RESERVE for an arbitrary role.

Release Notes - Mesos - Version 1.0.0
-------------------------------------
This release contains the following new features:
* Scheduler and Executor v1 HTTP APIs are now considered stable.
* [MESOS-4791] - **Experimental** support for v1 Master and Agent APIs. These
APIs let operators and services (monitoring, load balancers) send HTTP
requests to '/api/v1' endpoint on master or agent. See
`docs/operator-http-api.md` for details.
* [MESOS-4828] - **Experimental** support for a new `disk/xfs' isolator
has been added to isolate disk resources more efficiently. Please refer to
docs/mesos-containerizer.md for more details.
* [MESOS-4355] - **Experimental** support for Docker volume plugin. We added a
new isolator 'docker/volume' which allows users to use external volumes in
Mesos containerizer. Currently, the isolator interacts with the Docker
volume plugins using a tool called 'dvdcli'. By speaking the Docker volume
plugin API, most of the Docker volume plugins are supported.
* [MESOS-4641] - **Experimental** A new network isolator, the
`network/cni` isolator, has been introduced in the `MesosContainerizer`. The
`network/cni` isolator implements the Container Network Interface (CNI)
specification proposed by CoreOS. With CNI the `network/cni` isolator is
able to allocate a network namespace to Mesos containers and attach the
container to different types of IP networks by invoking network drivers
called CNI plugins.
* [MESOS-2948, MESOS-5403] - The authorizer interface has been refactored in
order to decouple the ACLs definition language from the interface.
It additionally includes the option of retrieving `ObjectApprover`. An
`ObjectApprover` can be used to synchronously check authorizations for a
given object and is hence useful when authorizing a large number of objects
and/or large objects (which need to be copied using request based
authorization). NOTE: This is a **breaking change** for authorizer modules.
* [MESOS-5405] - The `subject` and `object` fields in authorization::Request
have been changed from required to optional. If either of these fields is
not set, the request should only be authorized if any subject/object should
be allowed.
NOTE: This is a semantic change for authorizer modules.
* [MESOS-4931, MESOS-5709, MESOS-5704] - Authorization based HTTP endpoint
filtering enables operators to restrict what part of the cluster state a
user is authorized to see.
Consider for example the `/state` master endpoint: an operator can now
authorize users to only see a subset of the running frameworks, tasks, or
executors. The following endpoints support HTTP endpoint filtering:
'/state', '/state-summary', '/tasks', '/frameworks','/weights',
and '/roles'. Additonally the following v1 API calls support filtering:
'GET_ROLES','GET_WEIGHTS','GET_FRAMEWORKS', 'GET_STATE', and 'GET_TASKS'.
* [MESOS-4909] - Tasks can now specify a kill policy. They are best-effort,
because machine failures or forcible terminations may occur. Currently, the
only available kill policy is how long to wait between graceful and forcible
task kill. In the future, more policies may be available (e.g. hitting an
HTTP endpoint, running a command, etc). Note that it is the executor's
responsibility to enforce kill policies. For executor-less command-based
tasks, the kill is performed via sending a signal to the task process:
SIGTERM for the graceful kill and SIGKILL for the forcible kill. For docker
executor-less tasks the grace period is passed to 'docker stop --time'. This
feature supersedes the '--docker_stop_timeout', which is now deprecated.
* [MESOS-4908] - The task kill policy defined within 'TaskInfo' can now be
overridden when the scheduler kills the task. This can be used by schedulers
to forcefully kill a task which is already being killed, e.g. if something
went wrong during a graceful kill and a forcible kill is desired. Note that
it is the executor's responsibility to honor the 'Event.kill.kill_policy'
field and override the task's kill policy and kill policy from a previous
kill task request. To use this feature, schedulers and executors must
support HTTP API; use the '--http_command_executor' agent flag to ensure
the agent launches the HTTP API based command executor.
* [MESOS-4949] - The executor shutdown grace period can now be configured in
`ExecutorInfo`, which overrides the agent flag. When shutting down an
executor the agent will wait in a best-effort manner for the grace period
specified here before forcibly destroying the container. The executor must
not assume that it will always be allotted the full grace period, as the
agent may decide to allot a shorter period and failures / forcible
terminations may occur. Together with kill policies this gives frameworks
flexibility around how to clean up tasks and executors.
* [MESOS-3094] - **Experimental** support for launching mesos tasks on
Windows. Note that there are no isolation guarantees provided yet.
* [MESOS-4090] - The `mesos.native` python module has been split into two,
`mesos.executor` and `mesos.scheduler`. This change also removes
un-necessary 3rd party dependencies from `mesos.executor` and
`mesos.scheduler`. `mesos.native` still exists, combining both modules for
backwards compatibility with existing code.
* [MESOS-1478] - Phase I of the Slave to Agent rename is complete. To support
the rename, new duplicate flags (e.g., --agent_reregister_timeout), new
binaries (e.g., mesos-agent) and WebUI sandbox links have been added. All
the logging output has been updated to use the term 'agent' now. Flags,
binaries and scripts with 'slave' keyword have been deprecated (see
"Deprecations section below").
* [MESOS-4312] - **Experimental** support for building and running mesos on
IBM PowerPC platform.
* [MESOS-4189] - Weights for resource roles can now be configured dynamically
via the new '/weights' endpoint on the master.
* [MESOS-4424] - Support for using Nvidia GPUs as a resource in the
Mesos "unified" containerizer. This support includes running containers
with and without filesystem isolation (i.e. running both imageless
containers as well as containers using a docker image). Frameworks must
opt-in to receiving GPU resources via the GPU_RESOURCES framework
capability (see the scarce resource problem in MESOS-5377). We support
'nvidia-docker'-style docker containers by injecting a volume that
contains the Nvidia libraries / binaries when the docker image has
the 'com.nvidia.volumes.needed' label. Support for the docker
containerizer will come in a future release.
* [MESOS-5724] - SSL certificate validation allows for additional IP address
subject alternative name extension verification.
Deprecations:
* [MESOS-2281] - Deprecated the plain text format for credentials in favor of
the JSON format.
* [MESOS-4910] - Deprecate the --docker_stop_timeout agent flag.
* [MESOS-5001] - The 'allocator/event_queue_dispatches' metric is now
deprecated in favor 'of allocator/mesos/event_queue_dispatches'.
* [MESOS-5029] - Deprecated the ExecutorInfo.source field in favor of
ExecutorInfo.labels.
* [MESOS-3781] - Deprecated flags with keyword 'slave' in favor of 'agent'.
* [MESOS-3779] - Deprecated sandbox links with 'slave' keyword in the WebUI.
* [MESOS-3784] - Deprecated `slave` subcommand for mesos-cli.
* [MESOS-5155] - Deprecated `SetQuota` and `RemoveQuota` ACLs. This change is
applicable to the local authorizer as well as any custom authorizer module.
* [MESOS-5666] - Deprecated camel cased `taskInfo` and `executorInfo` in
isolator `ContainerConfig`.
* [MESOS-5863] - Deprecated `SSL_*` environment variables used by libprocess
SSL support in favor of using `LIBPROCESS_SSL_*`.
Additional API Changes:
* [MESOS-4580] - Returning `202` (Accepted) for /reserve and related endpoints.
* [MESOS-4735] - Added 'output_file' field to CommandInfo.URI in Scheduler API
and v1 Scheduler HTTP API.
* [MESOS-5014] - Changed Call and Event Type enums in scheduler.proto
from required to optional for the purpose of backwards compatibility.
* [MESOS-5015] - Changed Call and Event Type enums in executor.proto
from required to optional for the purpose of backwards compatibility.
* [MESOS-5029] - Added 'labels' to ExecutorInfo.
* [MESOS-5030] - Added non-terminal task metadata to the container resource
usage information.
* [MESOS-5408] - Deleted the /observe HTTP endpoint.
* [MESOS-4843, MESOS-5150, MESOS-5286, MESOS-5335, MESOS-5336] - Authorization
has been added to the '/metrics/snapshot', '/logging/toggle', '/quota',
'/files/browse', '/files/download', '/files/read', '/flags', and
'/containers' endpoints. If a Mesos cluster has authorization enabled, these
endpoints now require that ACLs be set to authorize principals to access
them. Note that the '/metrics/snapshot' and '/files/*' endpoints are used by
the web UI, and thus using the web UI in a cluster with authorization
enabled will require that ACLs be set appropriately.
* [MESOS-5064] - Remove default value for the agent `work_dir`. This flag is
now required, and the agent will exit immediately if it is not provided.
* [MESOS-5637] - Authorized endpoints consistently return `503` (Service
Unavailable) instead of `500` (Internal Server Error) when the authenticator
or the authorizer fails to process the request.
* [MESOS-5657] - Executors should not inherit environment variables from the
agent.
* [MESOS-5680] - We should not 'chown -R' on persistent volumes every time
container tries to use it.
* [MESOS-5642] - Namespace and header file of `Allocator` has been moved to
be consistent with other packages.
* [MESOS-5851] - The flag `--authenticate_http` has been deprecated in favor
of `--authenticate_http_readwrite`. This new flag enables authentication for
all HTTP endpoints which support authentication and allow modification of
the state of the cluster. A new flag has also been added,
`--authenticate_http_readonly`, which enables authentication for those
authenticatable endpoints that cannot be used to modify the cluster state.
* [MESOS-5833] - Disable the experimental `registry_strict` master flag.
3rd Party Upgrades:
* [MESOS-4805] - Upgraded vendored ry-http-parser-1c3624a to nodejs/http-parser 2.6.1.
