qiuliang created YARN-9437: ------------------------------ Summary: RMNodeImpls occupy too much memory and causes RM GC to take a long time Key: YARN-9437 URL: https://issues.apache.org/jira/browse/YARN-9437 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Affects Versions: 2.9.1 Reporter: qiuliang Attachments: 1.png, 2.png, 3.png
We use hadoop-2.9.1 in our production environment with 1600+ nodes. 95.63% of RM memory is occupied by RMNodeImpl. Analysis of RM memory found that each RMNodeImpl has approximately 14M. The reason is that there is a 13W+ completedcontainers in each RMNodeImpl that has not been released. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
