Stefan Richter created FLINK-9388:
-------------------------------------
Summary: Inconsistency in job shutdown produces confusing log
message
Key: FLINK-9388
URL: https://issues.apache.org/jira/browse/FLINK-9388
Project: Flink
Issue Type: Bug
Components: TaskManager
Affects Versions: 1.5.0, 1.6.0
Reporter: Stefan Richter
I found some logged exceptions in a user log that occurred during shutdown in
the context of latency markers. Those exceptions are most certainly not a real
problem, but can be confusing to users, so maybe we can get rid of them.
