Thank you. > 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 > Priority: Minor > Attachments: 1.png, 2.png, 3.png, YARN-9437-v1.txt > > > 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.
