Wei Zheng commented on HIVE-12441:
----------------------------------
This essentially will avoid having too much unnecessary logging for non-ACID
table, especially in extreme cases where there are hundreds of thousands of
transactions
> Driver.acquireLocksAndOpenTxn() should only call recordValidTxns() when needed
> ------------------------------------------------------------------------------
