--------------------------------------------
Status: Patch Available (was: Open)
> [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
>
> Attachments: HOD-LOG-ROTATION.1.txt, HOD-LOG-ROTATION.txt
>
>
> 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.
