[jira] [Created] (FLINK-10214) why is job applying as many TMs as default parallelism when starting, each parallelism is 1
lzh9 created FLINK-10214:
Summary: why is job applying as many TMs as default parallelism when starting, each parallelism is 1
Issue Type: Task
Components: Cluster Management, TaskManager, YARN
Affects Versions: 1.5.0
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?
