---------------------------------------
Summary: Dispatcher should only block job submission during
recovery
Key: FLINK-10078
URL: https://issues.apache.org/jira/browse/FLINK-10078
Project: Flink
Issue Type: Improvement
Affects Versions: 1.5.0
Reporter: Joey Echeverria
The Dispatcher currently doesn't confirm leadership until all jobs are
recovered. This prevents any operations that require an active Dispatcher from
working until after job recovery. This is primarily done to prevent race
conditions between client retries and recovering jobs. An alternative approach
would be to only block job submission while recovery is happening.
Note: we also need to check that no other RPCs change the internal state in
such a way that it interferes with the job recovery.
