      Description

      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.
