Release Notes - Mesos - Version 1.10.0
--------------------------------------------
This release contains the following highlights:
* Container resource bursting has been supported on Linux. Frameworks are
now able to specify CPU and memory limits for tasks (separately from
resource requests) and also the level of isolation they desire when
launching task groups - CPU and memory may be isolated at the executor
container level, or the task container level (MESOS-10001).
* Executors can now use a Unix domain socket to connect to an agent, instead
of connecting via TCP (MESOS-10034).
* Existing reservations can now be modified via the RESERVE_RESOURCES
master API call (MESOS-9981).
* Performance of read-only V1 operator API calls has been improved by
introducing direct serialization into JSON/protobuf and extending the
batching mechanism to parallel processing of these calls by the master
(similarly to `/state` endpoint). This brings V1 operator API performance
on par with older HTTP endpoints (MESOS-10026, MESOS-9497).
* **Breaking change** for authorizer modules: authorizers are now required
to implement a method for returning `ObjectApprover`s that are valid
throughout all of their lifetime. For framework and operator API subscriber
principals the set of `ObjectAprover`s is now requested from the authorizer
only once per subscription (MESOS-10056, MESOS-10057).
Additional API Changes:
* Quota can now be set on the default `*` role.
* Quota consumption metrics are now exposed by the allocator.
Unresolved Critical Issues:
* [MESOS-10066] - mesos-docker-executor process dies when agent stops. Recovery fails when agent returns
* [MESOS-10011] - Operation feedback with stale agent ID crashes the master
* [MESOS-9967] - Authorization header is missing when using a default registry
* [MESOS-9609] - Master check failure when marking agent unreachable
* [MESOS-9579] - ExecutorHttpApiTest.HeartbeatCalls is flaky.
* [MESOS-9536] - Nested container launched with non-root user may not be able to write to its sandbox via the environment variable `MESOS_SANDBOX`
* [MESOS-9500] - spark submit with docker image on mesos cluster fails.
* [MESOS-9426] - ZK master detection can become forever pending.
* [MESOS-9393] - Fetcher crashes extracting archives with non-ASCII filenames.
* [MESOS-9365] - Windows - GET_CONTAINERS API call causes the Mesos agent to fail
* [MESOS-9355] - Persistence volume does not unmount correctly with wrong artifact URI
* [MESOS-9352] - Data in persistent volume deleted accidentally when using Docker container and Persistent volume
* [MESOS-9053] - Network ports isolator can falsely trigger while destroying containers.
* [MESOS-9006] - The agent's GET_AGENT leaks resource information when using authorization
* [MESOS-8840] - `cpu.cfs_quota_us` may be accidentally set for command task using docker during agent recovery.
* [MESOS-8803] - Libprocess deadlocks in a test.
* [MESOS-8679] - "If the first KILL stuck in the default executor, all other KILLs will be ignored."
* [MESOS-8608] - RmdirContinueOnErrorTest.RemoveWithContinueOnError fails.
* [MESOS-8257] - "Unified Containerizer ""leaks"" a target container mount path to the host FS when the target resolves to an absolute path"
* [MESOS-8256] - Libprocess can silently deadlock due to worker thread exhaustion.
* [MESOS-8096] - Enqueueing events in MockHTTPScheduler can lead to segfaults.
* [MESOS-8038] - Launching GPU task sporadically fails.
* [MESOS-7971] - PersistentVolumeEndpointsTest.EndpointCreateThenOfferRemove test is flaky
* [MESOS-7911] - Non-checkpointing framework's tasks should not be marked LOST when agent disconnects.
* [MESOS-7748] - Slow subscribers of streaming APIs can lead to Mesos OOMing.
* [MESOS-7721] - Master's agent removal rate limit also applies to agent unreachability.
* [MESOS-7566] - Master crash due to failed check in DRFSorter::remove
* [MESOS-7386] - Executor not cleaning up existing running docker containers if external logrotate/logger processes die/killed
* [MESOS-6285] - Agents may OOM during recovery if there are too many tasks or executors
* [MESOS-5989] - Libevent SSL Socket downgrade code accesses uninitialized memory / assumes single peek is sufficient.
All Resolved Issues:
** Bug
* [MESOS-621] - `HierarchicalAllocatorProcess::removeSlave` doesn't properly handle framework allocations/resources
* [MESOS-4996] - 'containerizer->update' will always fail after killing a docker container.
* [MESOS-7217] - CgroupsIsolatorTest.ROOT_CGROUPS_CFS_EnableCfs is flaky.
* [MESOS-7639] - Oversubscription could crash the master due to CHECK failure in the allocator
* [MESOS-8537] - Default executor doesn't wait for status updates to be ack'd before shutting down
* [MESOS-8877] - Docker container's resources will be wrongly enlarged in cgroups after agent recovery
* [MESOS-9337] - Hook manager implementation is missing mutex acquisition in several places.
* [MESOS-9847] - Docker executor doesn't wait for status updates to be ack'd before shutting down.
* [MESOS-9889] - Master CPU high due to unexpected foreachkey behaviour in Master::__reregisterSlave.

* [MESOS-9975] - Sorter may leak clients allocations.
* [MESOS-9978] - Nvml isolator cannot be disabled which makes it impossible to exclude non-free code
* [MESOS-9980] - HierarchicalAllocatorTest.MaintenanceInverseOffers is flaky
* [MESOS-10007] - Command executor can miss exit status for short-lived commands due to double-reaping.
* [MESOS-10008] - Very large quota values can crash master.
* [MESOS-10015] - updateAllocation() can stall the allocator with a huge number of reservations on an agent.
* [MESOS-10018] - Duplicate tasks if agent partitioned during maintenance down
* [MESOS-10023] - Allocator method dispatches can be reordered (relative to scheduler API calls which triggered them).
* [MESOS-10041] - Libprocess SSL verification can leak memory
* [MESOS-10083] - Authorizing invalid operation can result in declined authorization.
* [MESOS-10084] - Detecting whether executor is generated for command task should work when the launcher_dir changes

Release Notes - Mesos - Version 1.9.0
-------------------------------------
This release contains the following highlights:
* Maintenance:
* Added new APIs to support automatic node draining via operator APIs.
This serves as an alternative to framework-assisted draining using
maintenance primitives. (MESOS-9753)
* Resource Management:
* Support for quota limits has been added. The existing quota guarantees
are deprecated in favor of using limits (and in the future, priorities).
* Security
* A new libprocess flag `--hostname_validation_scheme` has been added.
This allows users to enable a new RFC 6125-compliant hostname verification
scheme based on primitives provided by OpenSSL. This will also improve
performance by getting rid of all reverse DNS lookups. (MESOS-9784)
* The use of anonymous cipher suites is now disallowed when TLS certificate
verification is enabled. (MESOS-9810)
* Containerization:
* A new `--docker_ignore_runtime` flag has been added. This causes the agent
to ignore any runtime configuration present in Docker images. (MESOS-9760)
* Add no-new-privileges isolator. A new Linux isolator has been added to
support enabling the no_new_privs process control flag. (MESOS-9770)
* The Mesos containerizer now masks sensitive paths in `/proc` for
containers that do not share the host's PID namespace. (MESOS-9771)
* The Mesos containerizer now supports configurable IPC namespace and
/dev/shm. Container can be configured to have a private IPC namespace
and /dev/shm or share them from its parent, and the size of its private
/dev/shm is also configurable. (MESOS-9795)
* The Mesos containerizer now includes ephemeral overlayfs storage in the
task disk quota as well as sandbox storage. (MESOS-9900)
* A new `/containerizer/debug` HTTP endpoint has been added. This endpoint
exposes debug information for the Mesos containerizer. At the moment, it
returns a list of pending operations related to Isolators and Launchers.
(MESOS-9756)
Additional API Changes:
* Mesos components will now forego TLS certificate validation for incoming
connections, unless `LIBPROCESS_SSL_REQUIRE_CERT` is set to true.
* The `Socket::connect(const Address&)` member function will now abort the
program when called on a `LibeventSSLSocket`. Instead, the new overload
`Socket::connect(const Address&, const TLSClientConfig&)` must be used.
NOTE: This new overload is only available when libprocess is compiled
with `--enable-ssl`.

Release Notes - Mesos - Version 1.8.0
-------------------------------------
This release contains the following highlights:
* Performance Improvements:
* Frameworks can now specify the minimum resource quantities needed
in an offer, which acts as an override of the global
`--min_allocatable_resources` master flag. Updating schedulers to
specify this field improves multi-scheduler scalability as it
reduces the amount of offers declined from having insufficient
resource quantities. Note that this feature currently requires that
the scheduler re-subscribes each time it wants to mutate the
minimum resource quantity offer filter information, see MESOS-7258.
* The batching mechanism used for requests to the master's `/state`
endpoint was extending to other read-only master endpoints like
`/state-summary`, `/frameworks`, `/roles`, etc. (see MESOS-9158)
In addition, responses for multiple concurrent requests to read-only master
endpoints are now only computed once in cases where it can be guaranteed
that all responses would be equal. (see MESOS-9224)
This should significantly increase master responsiveness under
heavy load.
* Allocator cycle time is significantly decreased (around 40% for a
small size cluster and up to 70% for larger clusters) when quota is
used. This greatly narrows the allocator performance gap between
quota and non-quota usage scenarios.
* CLI
* The new Mesos CLI now offers the task subcommand. The first
command, attach, allows you to attach your terminal to a running
task launched with a tty. The second command, exec, launches a
new nested container inside a running task. To build the CLI,
use the flag `--enable-new-cli` with Autotools and
`-DENABLE_NEW_CLI=1` with CMake on MacOS or Linux.
* Operation Feedback:
* V1 schedulers can now receive operation feedback for operations on agent
default resources, i.e. normal cpu, memory, and disk. This means that the
v1 scheduler API's operation feedback feature can now be used for all
non-task-launch operations (any offer operations except for LAUNCH and
LAUNCH_GROUP) on any type of resources.
* The experimental operation feedback API for v1 schedulers made a breaking
change: the RECONCILE_OPERATIONS call no longer returns a 200 OK response
with a body containing the full reconciliation results. Instead, a
successful request now returns 202 Accepted, and a series of operation
status updates are sent on the scheduler's event stream to satisfy the
reconciliation request. This is similar to the way in which the master
replies to requests for task status reconciliation.
* Containerization:
* [MESOS-9029] - New `linux/seccomp` isolator: Containers launched
by Mesos containerizer can be sandboxed by enabling filtering of
system calls using a configurable policy.
* [MESOS-9675] - Support pulling docker images with docker manifest
V2 Schema2 on Mesos Containerizer.
* [MESOS-9133] - Support custom port range option to the `network/ports`
isolator. Added the `--container_ports_isolated_range` flag to the
`network/ports` isolator. This allows the operator to specify a custom
port range to be protected by the isolator.
* [MESOS-5158] - Support XFS quota for persistent volumes. Added
persistent volume support to the `disk/xfs` isolator.
* [MESOS-9009] - Support an option to create non-existing host
paths for host path volume in Mesos Containerizer. Added a new
agent flag `--host_path_volume_force_creation` for the
`volume/host_path` isolator.
* Container Storage Interface (CSI):
* **Experimental** Supported the new CSI v1 API. Operators can deploy
plugins that are compatible to either CSI v0 or v1 to create persistent
volumes through storage local resource providers, and Mesos will
automatically detect which CSI versions are supported by the plugins.
Additional API Changes:
* [MESOS-9540] - Improved the experimental `DESTROY_DISK` operations so
frameworks can now deprovision any unwanted pre-provisioned CSI volume
directly, if they are authorized to perform `DESTROY_RAW_DISK` actions.
