------------------------------------
Summary: Race condition in Dispatcher with concurrent granting and
revoking of leaderhship
Key: FLINK-9494
URL: https://issues.apache.org/jira/browse/FLINK-9494
Project: Flink
Issue Type: Bug
Components: Distributed Coordination
Affects Versions: 1.5.0
Reporter: Till Rohrmann
Fix For: 1.6.0, 1.5.1
The {{Dispatcher}} contains a race condition when an instance is granted
leadership and then quickly afterwards gets the leadership revoked. The problem
is that we don't check in the recovered jobs future callback that we still have
the leadership. This can lead to a corrupted state of the {{Dispatcher}}.
