Syed S. Albiz commented on HIVE-2335:
-------------------------------------
This change will likely break the change introduced in HIVE-2138, so it will be
smoother to have this one get in, and then modify the patch in 2138 to use a
more robust testcase to ensure that indexes are actually used
> Indexes are still automatically queried when out of sync with their source
> tables

> The automatic index usage does not check whether or not the indexes are still
> up-to-date when generating the index queries. This can be addressed in two
> stages, the first is to add a check before generating the index query to
> ensure that the index is still valid. The next stage may be to add some sort
> of mode where indexes are automatically updated on table writes.
