-------------------------------------
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.
