tartarus commented on FLINK-18663:
----------------------------------
[~trohrmann] the JobManager's log is too large，so I remove some yarn and
container’s log.
{{AbstractHandler.terminationFuture}} has not complete, because
AbstractHandler.inFlightRequestTracker Cannot be cleared.
[^jobmanager.log.noyarn.tar.gz]
I add the log you tell me , you can filter '#####' , the {{log.info("Shutting
RestServerEndpoint down internally")}} dosen't happen ,because
{{org.apache.flink.runtime.rest.handler.job.JobsOverviewHandler}} not close yet.
and {{org.apache.flink.runtime.rest.handler.job.JobsOverviewHandler}} not close
because {{AbstractHandler.inFlightRequestTracker}} not cleared, because the
exception on job from SCHEDULED to DEPLOYING

{code}
I am not very clear why {{FlinkHttpObjectAggregator}} was null，but,
{{FlinkHttpObjectAggregator here}} is only used to obtain maxContentLength, so
why not pass {{RestHandlerConfiguration}} or
{{RestServerEndpointConfiguration}} as construction parameters to
AbstractHandler, then we can obtain some other config too, I feel more flexible
like this.
But this is very redundant, after all, most of the parameters are not used.
