Subject [jira] [Resolved] (YARN-149) [Umbrella] ResourceManager (RM) Fail-over
Date Sun, 03 May 2015 01:50:12 GMT

     [ https://issues.apache.org/jira/browse/YARN-149?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli resolved YARN-149.
------------------------------------------
    Resolution: Fixed

Resolving this umbrella JIRA. RM failover has largely been complete/stable in YARN since this
ticket was opened. And as new requirements/bugs come in, we can open new tickets.
- Will leave the open sub-tasks as they are.
- No fix-version as this was done across releases.

RM instance so that we can have RM HA. Work includes leader election, transfer of control
to leader and client re-direction to new leader.
