[jira] [Created] (MAPREDUCE-4575) Add an option to drain the JobTracker jobs for upgrades

Arun C Murthy created MAPREDUCE-4575:
----------------------------------------

             Summary: Add an option to drain the JobTracker jobs for upgrades
                 Key: MAPREDUCE-4575
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4575
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Arun C Murthy
            Assignee: Arun C Murthy


Following on from MAPREDUCE-4328 it will be useful to allow an option to drain the JobTracker so that it will finish up existing jobs and not accept new ones.

This is particularly useful during upgrades.

Thank you Arun, finally you are convinced that some sort of decommissioning is required for JT and TT.
