[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.
