Timothy Farkas commented on DRILL-5967:
---------------------------------------

The majority of the work on this ticket will actually go into writing a unit 
test. As it is the PartitionSender is not unit testable. I will do some 
refactoring to be able to ock data tunnels so that I can write a standalone 
unit test. Hopefully future bugs in the PartitionSenders can benefit from this 
work.
