Eugene Koifman commented on HIVE-12366:

committed to branch-1
[~sershe] this wasn't marked for 2.0 but would be good to add.  Is that OK?

> Currently there is a gap between the time locks acquisition and the first heartbeat being
sent out. Normally the gap is negligible, but when it's big it will cause query fail since
