Gopal V commented on HIVE-19446:
--------------------------------
Lots of unrelated failures (failed for 3+ runs), row-order is different for
tez_dynpart_hashjoin_1.q, but I don't think it is related directly to this
patch, might be a flaky test ([~jdere] confirm?).
LGTM - +1
> QueryCache: Transaction lists needed for pending cache entries

> Hive query-cache needs a transactional list, even when the entry is pending
> state so that other identical queries with the same transactional state can
> wait for the first query to complete, instead of triggering their own
> instance.
