--------------------------------------
bq. Anybody reported this issue before.
Not that I'm aware of.
Have you tried an official Flink release? Can this problem be reproduced?
> No Slots available exception in Apache Flink Job Manager while Scheduling
> -------------------------------------------------------------------------
>
> Key: FLINK-17560
> URL: https://issues.apache.org/jira/browse/FLINK-17560
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.8.3
> Environment: Flink verson 1.8.3
> Session cluster
> Reporter: josson paul kalapparambath
> Priority: Major
> Attachments: jobmgr.log, threaddump-tm.txt, tm.log
>
>
> Set up
> ------
> Flink verson 1.8.3
> Zookeeper HA cluster
> 1 ResourceManager/Dispatcher (Same Node)
> 1 TaskManager
> 4 pipelines running with various parallelism's
> Issue
> ------
> Occationally when the Job Manager gets restarted we noticed that all the
> pipelines are not getting scheduled. The error that is reporeted by the Job
> Manger is 'not enough slots are available'. This should not be the case
> because task manager was deployed with sufficient slots for the number of
> pipelines/parallelism we have.
> We further noticed that the slot report sent by the taskmanger contains solts
> filled with old CANCELLED job Ids. I am not sure why the task manager still
> holds the details of the old jobs. Thread dump on the task manager confirms
> that old pipelines are not running.
> I am aware of https://issues.apache.org/jira/browse/FLINK-12865. But this is
> not the issue happening in this case.
