------------------------------------
Summary: JobManager isolation in session mode
Key: FLINK-9537
URL: https://issues.apache.org/jira/browse/FLINK-9537
Project: Flink
Issue Type: Improvement
Components: Distributed Coordination
Affects Versions: 1.5.0, 1.6.0
Reporter: Till Rohrmann
Currently, all {{JobManagers}} are executed in the same process which also runs
the {{Dispatcher}} component when using the session mode. This is problematic,
since the {{JobManager}} also executes user code. Consequently, a bug in a
single Flink job can cause the failure of the other {{JobManagers}} running in
the same process. In order to avoid this we should add the functionality to run
each {{JobManager}} in its own process.
