0.11.0 Released

The latest Apache Aurora release, 0.11.0, is now available for download. Here are some highlights in this release:

New/updated

• Added built-in support for log rotation of task stderr/stdout.
• Added support for performing task health checks using a shell command.
• Added support for accepting an executor configuration in JSON via scheduler command line argument --custom_executor_config which will override all other the command line arguments and default values pertaining to the executor.
• Added a new scheduler flag --framework_announce_principal to support use of authorization and rate limiting in Mesos.
• Upgraded Mesos to 0.24.1.

Deprecations and removals

• The client-side updater has been removed, along with the CLI commands that used it: aurora job update and aurora job cancel-update. Users are encouraged to take advantage of scheduler-driven updates (see aurora update -h for usage), which has been a stable feature for several releases.
• To support configuration of shell-based health checkers, the HealthCheckConfig schema has been restructured to more cleanly allow configuring varied types of health checkers. The following fields from HealthCheckConfig are now deprecated: endpoint, expected_response, expected_response_code in favor of setting them as part of an HttpHealthChecker.
• In the scheduler API, the field JobUpdateSettings.maxWaitToInstanceRunningMs (UpdateConfig.restart_threshold in client-side configuration) is now deprecated. This setting was brittle in practice, and is ignored by the 0.11.0 scheduler.

Full release notes are available in the release CHANGELOG.
