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.
