------------------------------------
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.
