Alexander Kolbasov commented on HIVE-18526:
-------------------------------------------
The patch in branch2 uses DataNucleus way of generating {{SELECT FOR UPDATE:}}
{code:java}
query.setSerializeRead(true);
{code}
This is simpler, then the original fix and works with all DB backends.
I wrote modified version of the test to ensure correctness for concurrent
updates.
