-------------------------------
Summary: Job may try to leave SUSPENDED state in
ExecutionGraph#failJob()
Key: FLINK-19806
URL: https://issues.apache.org/jira/browse/FLINK-19806
Project: Flink
Issue Type: Bug
Reporter: Zhu Zhu
Assignee: Zhu Zhu
{{SUSPENDED}} is a terminal state which a job is not supposed to leave this
state once entering. However, {{ExecutionGraph#failJob()}} did not check it and
may try to transition a job out from {{SUSPENDED}} state. This will cause
unexpected errors and may lead to JM crash.
The problem can be visible if we rework {{ExecutionGraphSuspendTest}} to be
based on {{DefaultScheduler}}.
We should harden the check in {{ExecutionGraph#failJob()}}.
