----------------------------------
Summary: Fix memory leak and finish app trigger in AMRMProxy
Key: YARN-6565
URL: https://issues.apache.org/jira/browse/YARN-6565
Project: Hadoop YARN
Issue Type: Bug
Reporter: Botong Huang
Assignee: Botong Huang
Priority: Minor
Two issues in AMRMProxy:
1. When application finishes, AMRMTokenSecretManager is not updated to remove
related data, leading to memory leak.
2. When we kill an application, we should remove the pipeline after the AM
container is killed.
FINISH_APPLICATION event is sent when the AM container is still being killed.
After we remove the pipeline, we might still get heartbeats from AM, triggering
exception messages.
Instead, we should wait for APPLICATION_RESOURCES_CLEANEDUP event, sent after
where the AM container is killed.
