Subject [jira] [Created] (HADOOP-8081) HOD Should Be Less Restrictive Over Options Passed To Resource Manager

HOD Should Be Less Restrictive Over Options Passed To Resource Manager

                 Key: HADOOP-8081
                 URL: https://issues.apache.org/jira/browse/HADOOP-8081
             Project: Hadoop Common
          Issue Type: Wish
          Components: contrib/hod
    Affects Versions: 1.0.0, 0.21.0
            Reporter: Ben Smithers
            Priority: Minor

At present, HOD requires any extra options passed to the resource manager to be of the form

This is quite restrictive. Considering Torque and qsub, this effectively limits the options
to a subset of the resource constraints, variable lists and additional attributes. Potentially
desirable attributes that cannot (to the best of my knowledge) be expressed:
 - Mailing options. Given than it may take some time for a long-running HOD job to be scheduled,
it would be useful to exploit the options (-m and -M) for notifying users
 - Other resource constraints, such as particular nodes or number of processors per node.
The format required by qsub(http://www.clusterresources.com/torquedocs/2.1jobsubmission.shtml#nodeExamples)
is incompatible with the format required by HOD. In practice, it would probably be desirable
to have these options specified via the command line as these may change per HOD job

I imagine some thought would be needed to balance flexibility whist not breaking the options
HOD sets by default.
