Subject [jira] Created: (MAPREDUCE-871) Job/Task local files have incorrect group ownership set by LinuxTaskController binary
Date Fri, 14 Aug 2009 08:23:14 GMT
Job/Task local files have incorrect group ownership set by LinuxTaskController binary
-------------------------------------------------------------------------------------

                 Key: MAPREDUCE-871
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-871
             Project: Hadoop Map/Reduce
          Issue Type: Sub-task
          Components: tasktracker
            Reporter: Vinod K V


HADOOP-4491 fixed the secure permissions of local files on a TT. While testing HADOOP-4491
on a cluster, [~karams] found out a bug. All the files/dirs have should be owned by the group
corresponding to the group owner of the task-controller binary (via using getegid()) which
in turn is a special group to which *only* TT user belongs. HADOOP-4491 incorrectly set it
to primary group of the TT via getgid(), and not the special group.
