Vinod Kumar Vavilapalli commented on YARN-556:
----------------------------------------------

> YARN-128 covered storing the state needed for the RM to recover critical information.
This umbrella jira will track changes needed to recover the running state of the cluster so
that work can be preserved across RM restarts.
