Zhijie Shen created YARN-3623:
---------------------------------
Summary: Having the config to indicate the timeline service version
Key: YARN-3623
URL: https://issues.apache.org/jira/browse/YARN-3623
Project: Hadoop YARN
Issue Type: Sub-task
Components: timelineserver
Reporter: Zhijie Shen
Assignee: Zhijie Shen
So far RM, MR AM, DA AM added/changed new config to enable the feature to write
the timeline data to v2 server. It's good to have a YARN
timeline-service.version config like timeline-service.enable to indicate the
version of the running timeline service with the given YARN cluster. It's
beneficial for users to more smoothly move from v1 to v2, as they don't need to
change the existing config, but switch this config from v1 to v2. And each
framework doesn't need to have their own v1/v2 config.
