Subject [jira] Created: (HADOOP-4389) allow use of Torque per-job temporary directories
Date Fri, 10 Oct 2008 18:39:44 GMT
allow use of Torque per-job temporary directories
-------------------------------------------------

                 Key: HADOOP-4389
                 URL: https://issues.apache.org/jira/browse/HADOOP-4389
             Project: Hadoop Core
          Issue Type: Improvement
          Components: contrib/hod
    Affects Versions: 0.18.1
            Reporter: David Chiang
            Priority: Minor


Torque can be configured to create a per-job temporary directory that will automatically be
cleaned up at the completion of a Torque job. At our site, we are strongly encouraged to use
this directory and not /tmp. The name of the per-job temp dir is in the environment variable
TMPDIR in the Torque job's environment. It would be very useful for HOD to be extended so
that one could write in hodrc:

[ringmaster]
temp-dir = $TMPDIR
work-dirs = $TMPDIR/1

[hodring]
temp-dir = $TMPDIR

such that $TMPDIR is evaluated inside the Torque job.
