Subject [jira] [Created] (YARN-1274) LCE fails to run containers that don't have resources to localize
Date Sat, 05 Oct 2013 00:20:42 GMT
Alejandro Abdelnur created YARN-1274:
----------------------------------------

             Summary: LCE fails to run containers that don't have resources to localize
                 Key: YARN-1274
                 URL: https://issues.apache.org/jira/browse/YARN-1274
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.1.1-beta
            Reporter: Alejandro Abdelnur
            Assignee: Alejandro Abdelnur
            Priority: Blocker


LCE container launch assumes the usercache/USER directory exists and it is owned by the user
running the container process.

But the directory is created only if there are resources to localize by the LCE localization
command, if there are not resourcdes to localize, LCE localization never executes and launching
fails reporting 255 exit code and the NM logs have something like:

{code}
