> tests whether the JDO persistence manager cache cleanup was performed
> correctly when a HiveMetaStoreClient executes an API call, and closes. It
> does this by ensuring that the cache object count before the API call, and
> after closing, are the same. However, there are some assumptions that are not
> always correct, and can cause flakiness.
> For example, lingering resources could be present from previous tests or from
> setup depending on how PTest runs it, and can cause the object count to
> sometimes be incorrect. We should rewrite this test to account for this
> flakiness that can occur.
