Subject [jira] [Created] (MAPREDUCE-5047) keep.failed.task.files=true causes job failure on secure clusters
Date Tue, 05 Mar 2013 21:08:13 GMT
Sandy Ryza created MAPREDUCE-5047:
-------------------------------------

             Summary: keep.failed.task.files=true causes job failure on secure clusters
                 Key: MAPREDUCE-5047
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5047
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: task, tasktracker
    Affects Versions: 1.1.1
            Reporter: Sandy Ryza
            Assignee: Sandy Ryza


To support IsolationRunner, split info is written to local directories.  This occurs inside
MapTask#localizeConfiguration, which is called both tasktracker and by the child JVM.  On
a secure cluster, the tasktacker's attempt to write it fails, because the tasktracker does
not have permission to write to the user's directory. It is likely that the call to localizeConfiguration
in the tasktracker can be removed.
