Subject [jira] [Updated] (YARN-556) RM Restart phase 2 - Work preserving restart
Date Fri, 23 Aug 2013 01:50:52 GMT

     [ https://issues.apache.org/jira/browse/YARN-556?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bikas Saha updated YARN-556:
----------------------------

    Attachment: Work Preserving RM Restart.pdf

Attaching a proposal with details. I may have missed writing something even though I thought
of it or may have missed something altogether. Will incorporate feedback as it comes. Will
soon start creating sub-tasks that make sense in a chronological ordering of work. Making
incremental progress while keeping the RM stable is the desired course of action (like YARN-128).

> 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.
