Jason Lowe commented on YARN-1311:
----------------------------------
The branch-2 build is broken, and it seems to be related to this change:
{noformat}
[ERROR] Failed to execute goal

It appears a similar compilation failure was fixed on trunk, but branch-2 is
still failing.

> Today, APP_ADDED and APP_REMOVED are sent to the scheduler. They are
> misnomers as schedulers only deal with AppAttempts today. This JIRA is for
> fixing their names so that we can add App-level events in the near future,
> notably for work-preserving RM-restart.
