Change subject: IMPALA-3499: Frontend cannot deserialize catalog-update topic 
more than 2GB.
......................................................................


Patch Set 4:

sorry just saw this.. Yes, Dan.

I saw exhaustive data loading hanging in previous patch set.. probably had 
something to do with catalog_service_id_ is 0:0 before the update sees the 
catalog object update.

I rearranged the topic order in the update to fix this. This passed core test. 
I am running exhaustive test with MAX_CATALOG_UPDATE_SIZE set to be 20kb, which 
should test the path very very frequently.
