---------------------------------------------------------------
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.

> Testing : log thread stacks when metastore fails to start

> 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 -
> {code}
> java.net.ConnectException: Connection refused
