Till Rohrmann commented on FLINK-13162:
---------------------------------------
I don't fully understand the problem [~zjffdu]. Is the problem that a
{{JobMaster}} needs to wait for 50s until an idle slot has been released by
another {{JobMaster}} if there are multiple jobs running in the same cluster?
> Default value of slot.idle.timeout is too large for batch job
> -------------------------------------------------------------

> URL: https://issues.apache.org/jira/browse/FLINK-13162
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Configuration, Runtime / Coordination
> Affects Versions: 1.9.0
> Reporter: Jeff Zhang
> Priority: Major
>
> The default value of slot.idle.timeout is 50 seconds, it is too large for
> batch job.
> It will cause downstream vertex unable to start even the upstream vertex is
> finished. It has to wait for 50 seconds. The default value of this kind of
> configuration doesn't make sense for batch job.
