Thanks, [~jcamachorodriguez] and [~jdere]. I went thru the doc and is still
unclear what mechanism was decided to invalidate cache. Is this doc still work
in progress?

> Add a query results cache that can save the results of an executed Hive query
> for reuse on subsequent queries. This may be useful in cases where the same
> query is issued many times, since Hive can return back the results of a
> cached query rather than having to execute the full query on the cluster.
