Sandy Ryza commented on YARN-546:
---------------------------------
Thought about this again and I think the option is better as a YARN config.
Added yarn.scheduler.fair.event-log-enabled. If the need arises in the future
we can add controls in the allocations file for turning on and off different
types of logs.
> mapred.fairscheduler.eventlog.enabled removed from Hadoop 2.0

> Hadoop 1.0 supported an option to turn on/off FairScheduler event logging
> using mapred.fairscheduler.eventlog.enabled. In Hadoop 2.0, it looks like
> this option has been removed (or not ported?) which causes event logging to
> be enabled by default and there is no way to turn it off.
