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

Also increased the frequency of checks for metastore startup from every 10 sec to every sec. 1 sec pause should be more than enough to not consume too much of cpu resources on the machine, and it will help shave off a few seconds from the test runtime.

> 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 -
