------------------------------------
Summary: Exception thrown from JobMaster.startScheduling() may be
ignored.
Key: FLINK-20382
URL: https://issues.apache.org/jira/browse/FLINK-20382
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Affects Versions: 1.11.2
Reporter: Jiangjie Qin
Currently {{JobMaster.resetAndStartScheduler()}} invokes {{startScheduling()}}
in a {{thenRun}} clause without {{exceptionally}} or {{handle}} to handle
exceptions. The job may hang if an exception is thrown when starting
scheduling, e.g. failed to create operator coordinators.
