Brock Noland commented on HIVE-5068:
------------------------------------
Yeah agreed that appears to be the issue. I got around that using a persistence
delegate and then hit the same issue on another object. The current issue is
when we are using serialization to clone the query plan so there is no reason
we need to use xml encoder. Tomorrow I will try plain old java serialization.
