Subject [jira] [Commented] (YARN-71) Ensure/confirm that the NodeManager cleans up local-dirs on restart
Date Thu, 14 Mar 2013 06:20:15 GMT

    [ https://issues.apache.org/jira/browse/YARN-71?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13602080#comment-13602080

Vinod Kumar Vavilapalli commented on YARN-71:
---------------------------------------------

Some more comments:
 - In case of errors, can you say " need to be manually deleted" instead of just " need to
be deleted"?
 - Please add tests to
    -- verify fileCache and NM_PRIVATE_DIR deletion
    -- verify deleteHistoricalLocalDirs by rebooting NM multiple times when a previous deletion
was in progress

> We have to make sure that NodeManagers cleanup their local files on restart.
> It may already be working like that in which case we should have tests validating this.
