Johannes Zillmann commented on YARN-556:
----------------------------------------
Mmh, have a test-cluster where the resource-manager fails to start after a
crash. No matter if only the resource manager is started or the whole YARN, we
always getting following exception:

> Project: Hadoop YARN
> Issue Type: New Feature
> Components: graceful, resourcemanager, rolling upgrade
> Reporter: Bikas Saha
> Attachments: Work Preserving RM Restart.pdf,
> WorkPreservingRestartPrototype.001.patch, YARN-1372.prelim.patch
>
>
> 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.
