[jira] [Created] (YARN-3857) Memory leak in ResourceManager with
SIMPLE mode
mujunchao created YARN-3857:
-------------------------------
Summary: Memory leak in ResourceManager with SIMPLE mode
Key: YARN-3857
URL: https://issues.apache.org/jira/browse/YARN-3857
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 2.7.0
Reporter: mujunchao
Priority: Critical
We register the ClientTokenMasterKey to avoid client may hold an invalid ClientToken after RM restarts. In SIMPLE mode, we register Pair<ApplicationAttemptId, null> , But we never remove it from HashMap, as unregister only runing while in Security mode, so memory leak coming.
