------------------------------------

             Summary: Testing  : log thread stacks when metastore fails to start
                 Key: HIVE-13491
                 URL: https://issues.apache.org/jira/browse/HIVE-13491
             Project: Hive
          Issue Type: Bug
          Components: Test, Testing Infrastructure
            Reporter: Thejas M Nair
            Assignee: Thejas M Nair


Many tests are failing in ptest2 because metastore fails to startup in the expected time.
There is not enough information to figure out why the metastore startup failed/got hung in
the hive.log file. Printing the thread dumps when that happens would be useful.

The stack in test failure looks like this -
{code}
java.net.ConnectException: Connection refused
