------------------------------------
Summary: MiniCluster can deadlock at shut down
Key: FLINK-7279
URL: https://issues.apache.org/jira/browse/FLINK-7279
Project: Flink
Issue Type: Bug
Components: Tests
Affects Versions: 1.4.0
Reporter: Till Rohrmann
The {{MiniCluster}} can deadlock in case if the fatal error handler is called
while the {{MiniCluster}} shuts down. The reason is that the shut down happens
under a lock which is required by the fatal error handler as well. If now the
{{MiniCluster}} tries to shut down the underlying RPC service which waits for
all actors to terminate, it will never complete because one actor is still
waiting for the lock.
One solution would be to ignore the fatal error handler calls if the
{{MiniCluster}} is shutting down.
