[jira] [Created] (FLINK-5856) Need return redundant containers to
yarn for yarn mode
shuai.xu created FLINK-5856:
-------------------------------
Summary: Need return redundant containers to yarn for yarn mode
Key: FLINK-5856
URL: https://issues.apache.org/jira/browse/FLINK-5856
Project: Flink
Issue Type: Bug
Components: YARN
Reporter: shuai.xu
Assignee: shuai.xu
For flink on yarn mode, RM requests container from yarn according to the requirement of the JM. But the AMRMClientAsync used in yarn doesn't guarantee that the number of containers returned exactly equal to the number requested. So it need to record the number request by flink rm and return the redundant ones to yarn.
