----------------------------
Summary: 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
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?
