      Description

      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 for finding the root cause.

      The stack in test failure looks like this -

      java.net.ConnectException: Connection refused
      	at java.net.PlainSocketImpl.socketConnect(Native Method)
      	at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339)
