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 -
