----------------------------------
Summary: Misleading error messages when cancelling tasks
Key: FLINK-1577
URL: https://issues.apache.org/jira/browse/FLINK-1577
Project: Flink
Issue Type: Improvement
Components: Distributed Runtime
Affects Versions: master
Reporter: Ufuk Celebi
A user running a Flink version before bec9c4d ran into a job manager failure
(fixed in bec9c4d), which lead to restarting the JM and cancelling/clearing all
tasks on the TMs.
The logs of the TMs were inconclusive. I think part of that has been fixed by
now, e.g. there is a log message when cancelAndClearEverything is called, but
the task thread (RuntimeEnvironment) always logs an error when interrupted
during the run method -- even if the task gets cancelled.
I think these error messages are misleading and only the root cause is
important (i.e. non-failed tasks should be silently cancelled).
