[jira] [Updated] (YARN-2079) Recover NonAggregatingLogHandler state upon nodemanager restart

     [ https://issues.apache.org/jira/browse/YARN-2079?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jason Lowe updated YARN-2079:
-----------------------------
    Attachment: YARN-2079.patch

Patch that saves the state of scheduled LogDeleterRunnable objects to the state store and reschedules them upon recovery.  Added unit tests for both the leveldb state store changes and log handler recovery.
