[HOD] Make HOD to roll log files on the client 

                 Key: HADOOP-4060
                 URL: https://issues.apache.org/jira/browse/HADOOP-4060
             Project: Hadoop Core
          Issue Type: Bug
          Components: contrib/hod
            Reporter: Hemanth Yamijala
            Assignee: Vinod Kumar Vavilapalli
            Priority: Blocker
             Fix For: 0.18.1, 0.19.0

Currently HOD writes a log file on the client in the cluster directory, named hod-<username>.log.
This file is appended to for each run of hod allocation that runs on the same cluster directory.
Thus, the file can become quite large - particularly if the job is queued for a long time.
If there are problems with the HOD client subsequently, this could result in stale file handles
pointing to this large file, and cause disk space to fill up. Another problem is that a large
log file is usually unusable for a user.
