Subject [jira] [Updated] (YARN-253) Container launch may fail if no files were localized
Date Fri, 30 Nov 2012 21:37:59 GMT

     [ https://issues.apache.org/jira/browse/YARN-253?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tom White updated YARN-253:
---------------------------

    Attachment: YARN-253.patch

This fixes the problem by creating parent directories if they don't already exist. Without
the fix the test would fail about 4 times in 10; with the fix I didn't see a failure.

> This can be demonstrated with DistributedShell. The containers running the shell do not
have any files to localize (if there is no shell script to copy) so if they run on a different
NM to the AM (which does localize files), then they will fail since the appcache directory
does not exist.
