Interface: job_requeue_timeout

• Visibility: Public
• Change Control: Obsolete
• Synopsis: server attribute job_requeue_timeout, will now be used to send reply to the client that job couldn't be rerun within the time period and will continue to be in progress.
  
• Details:
  
  • server attribute job_requeue_timeout, does not have a clear specification as to what will happen to the job once the timeout is hit.
    
  • current behaviour is that once the timeout is hit, server returns an error to the client that the rerun process has timed out.
  • However, the server continues the process of rerunning the job even though an error is already returned to the client.
  • As this "timeout" is not aborting the rerun process, but leads to display a spurious message that the rerun has timed out, the behaviour is not correct.
    
  • PBS scheduler relies on the "delay" and if the API is made to return immediately, there are chances there will be over-subscription.
    
  • Hence, we would continue to have this delay/timeout in place, however, the server attribute job_requeue_timeout, will be marked obsolete.
  • The documentation will be changed to reflect that the attribute is obsolete and that the error message is spurious.
  • The error message will be changed to display that the rerun process is in progress. Exact words will be "qrerun: Response timed out. Job rerun request still in progress for <jobid>.<server>"
