lzh9 commented on FLINK-10214:
------------------------------
because it will apply 48*1, few minutes later it uses 8*6 instead, the purpose
is to start streaming as soon as possible?
> why is job applying as many TMs as default parallelism when starting, each
> parallelism is 1

> Key: FLINK-10214
> URL: https://issues.apache.org/jira/browse/FLINK-10214
> Project: Flink
> Issue Type: Task
> Components: Cluster Management, TaskManager, YARN
> Affects Versions: 1.5.0
> Reporter: lzh9
> Priority: Major
>
> If I set TM number=6, slot num each TM=8, memory each TM=4G, the job will
> apply 48 TMs, and use only one slot each, total memory usage is 192G. A few
> minutes later, it will release 40TMs, everything will be normal.
> Is there any reason about it?
