Changes from 2.4.0 to 2.5.0
Overview
The full changelog is available from GitHub at: 2.4.0...2.5.0
Support for Mesos 1.3.0
Chronos now uses libmesos 1.3.0, which should be compatible with at least Mesos 1.3.x and 1.2.x.
Updated many dependencies
The versions of many dependencies were bumped.
Added support for periods in job names
The job names can now contain letters ([a-zA-Z]), digits ([0-9]), dashes (-), underscores
(_), number signs (#), periods (.), and whitespace ([ \t\n\x0B\f\r]). They must match the
following regular expression: ([\w\s\.#_-]+)
Better support for custom executors
When using a custom executor, Chronos will now set the executor id to the job name and also include
the URIs in the CommandInfo proto.
Added support for specifying Docker parameters
It is now possible to specify arbitrary Docker parameters.
Check the REST API documentation for more details.
Changed the default framework name
The framework name doesn't include the version number anymore.
New API endpoints
The new /scheduler/leader endpoint makes it possible to get the current leader.
It is now possible to mark a job as successful via the /scheduler/job/success API endpoint.
If a job is marked successful, the success count +of the job is incremented, the latest successful
run time is updated, and all downstream dependencies are handled as if the job had completed
executing the code in a standard run.
Improved constraints
Chronos now supports the UNLIKE operator and it is possible to constraint jobs by hostname.
