> [~janulatha] fixed the problem, when multiple MetaStore tests are started on 
> the same machine, then they tried to reserve the same port. This caused 
> flakiness in the MetaStore tests run with the ptest framework. See: HIVE-18147
> I reviewed the HIVE-17980, and tried to make sure, that the fix remains in 
> every codepath. I was unsuccessful in it. :(
> This Jira aims to go through the MetaStore tests, and make sure all of them 
> is using the  {{startMetaStoreWithRetry}} method so the different tests will 
> not cause each other to fail. Also there were clashes not only in port 
> numbers, but warehouse directories as well, so this Jira should fix that also.
