> 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.
