-----------------------------------
Summary: Interrupted Exception within AsyncDispatcher leads to
user confusion
Key: YARN-139
URL: https://issues.apache.org/jira/browse/YARN-139
Project: Hadoop YARN
Issue Type: Bug
Components: api
Affects Versions: 2.0.2-alpha, 0.23.4
Reporter: Nathan Roberts
Successful applications tend to get InterruptedExceptions during shutdown. The
exception is harmless but it leads to lots of user confusion and therefore
could be cleaned up.
