["Vinod Kumar Vavilapalli (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-667?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vinod Kumar Vavilapalli reassigned YARN-667:
--------------------------------------------

    Assignee: Vinod Kumar Vavilapalli

So in summary, we will need to version
 - RM state store stuff
 - Aggregated logs uploaded by NM
 - NM directory structure: Either we can have
    -- One version file all of the directory strucuture
    -- multiple version files - one for dist-cache, one for others etc.
 - Even ShuffleHandler needs to be versioned as it runs inside NM. Similarly, the AuxServices data returned by StartContainer.
