> HIVE-18846 allows the results cache to refer to currently executing queries
> so that another query can wait for these results to become ready in the
> results cache. If the pending query fails then Hive will automatically skip
> the cache and do the full query compilation. Make a fix here so that if the
> pending query fails, Hive will still try to check the cache again in case the
> cache has another cached/pending result that can be used to answer the query.
