---------------------------------------
No, I mean to wait for a previous leadership operation to finish before
starting a new one.
> JobManagerRunner does not wait for suspension of JobMaster

> Project: Flink
> Issue Type: Bug
> Components: Distributed Coordination
> Affects Versions: 1.6.3, 1.7.1, 1.8.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Major
> Labels: pull-request-available

> Time Spent: 10m
> Remaining Estimate: 0h

> The {{JobManagerRunner}} does not wait for the suspension of the
> {{JobMaster}} to finish before granting leadership again. This can lead to a
> state where the {{JobMaster}} tries to start the {{ExecutionGraph}} but the
> {{SlotPool}} is still stopped.
> I suggest to linearize the leadership operations (granting and revoking
> leadership) similarly to the {{Dispatcher}}.
