Subject [jira] [Created] (FLINK-8629) Allow JobMaster to rescale jobs
Date Fri, 09 Feb 2018 20:11:00 GMT
Till Rohrmann created FLINK-8629:

             Summary: Allow JobMaster to rescale jobs
                 Key: FLINK-8629
                 URL: https://issues.apache.org/jira/browse/FLINK-8629
             Project: Flink
          Issue Type: New Feature
          Components: Distributed Coordination
    Affects Versions: 1.5.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.5.0

The {{JobMaster}} should be able to rescale a job or a subset of its operators. In order to
do that we have to expose RPC calls to trigger this action.

The rescaling works by first taking a savepoint, then suspending the old job, rescale it and
then restart it from the taken savepoint.
