Can someone please review this change ? It should help nail down the problem
with metastore startup in large number of tests.
This change impacts only the tests.
We have 30+ patches in the queue, and many runs are taking 3+hrs to finish.
Putting this in asap could help in reducing the number of failures in those
tests and might also give more clues on why the runs are taking so long.
> 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

> 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
> at java.net.PlainSocketImpl.socketConnect(Native Method)
