> Key: FLINK-10848
> URL: https://issues.apache.org/jira/browse/FLINK-10848
> Project: Flink
> Issue Type: Bug
> Components: YARN
> Affects Versions: 1.3.3, 1.4.2, 1.5.5, 1.6.2
> Reporter: Shuyi Chen
> Assignee: Shuyi Chen
> Priority: Major
> Labels: pull-request-available

> Currently, both the YarnFlinkResourceManager and YarnResourceManager do not call removeContainerRequest() on container allocation success. Because the YARN AM-RM protocol is not a delta protocol (please see YARN-1902), AMRMClient will keep all ContainerRequests that are added and send them to RM.
> In production, we observe the following that verifies the theory: 16 containers are allocated and used upon cluster startup; when a TM is killed, 17 containers are allocated, 1 container is used, and 16 excess containers are returned; when another TM is killed, 18 containers are allocated, 1 container is used, and 17 excess containers are returned.
