Andrey Klochkov reassigned YARN-1183: ------------------------------------- Assignee: Andrey Klochkov > 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 > Assignee: Andrey Klochkov > Attachments: YARN-1183--n2.patch, YARN-1183--n3.patch, > YARN-1183--n4.patch, YARN-1183.patch > > > 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 was sent by Atlassian JIRA (v6.1#6144)
