While looking at the fix for HIVE-16886, I noticed that DataNucleus provides a generic way of doing SELECT FOR UPDATE so it is possible to achieve this with just a single-line change rather then the big fix introduced by HIVE-16886.
What do people think about redoing the fix by using DataNucleus way? The fix is to do query = pm.newQuery(MNotificationNextId.class); query.setSerializeRead(true); - Alex
