Application not running message
Understanding the Application not running message from TEZ that appears
in the YARN application log prevents confusion when inspecting Hive queries.
During startup, HiveServer starts sessions that are available until
tez.session.am.dag.submit.timeout.secs expires, and then the Application
Masters are killed. HiveServer transparently restarts dead AMs on demand when you run another
query. HiveServer tries to clean up sessions from the Tez pool during shutdown. "Application
not running" message that looks something like this might appear in a stack trace
