Andrey Klochkov created YARN-1183: ------------------------------------- Summary: MiniYARNCluster shutdown takes several minutes intermittently Key: YARN-1183 URL: https://issues.apache.org/jira/browse/YARN-1183 Project: Hadoop YARN Issue Type: Bug Reporter: Andrey Klochkov
As described in MAPREDUCE-5501 sometimes M/R tests leave MRAppMaster java processes living for several minutes after successful completion of the corresponding test. There is a concurrency issue in MiniYARNCluster shutdown logic which leads to this. Sometimes RM stops before an app master sends it's last report, and then the app master keeps retrying for >6 minutes. In some cases it leads to failures in subsequent tests, and it affects performance of tests as app masters eat resources. -- This message is automatically generated by JIRA.
