Date Tue, 17 Jul 2018 14:39:00 GMT


Igor Kryvenko commented on HIVE-17683:


Hi Eugene. I did changes which you requested in your review, please review it when you will
have time for it.

Seems like failing of tests is not related again.

Thanks, Igor.

> Explore if it's possible to add info about what locks will be asked for to the query
> Lock acquisition (for Acid Lock Manager) is done in DbTxnManager.acquireLocks() which
is called once the query starts running.  Would need to refactor that.
