Review comment:
       Most of the write path is mocked out, Hive queries are not committed to 
test writes in this test class. That means no optimizers can run either, and 
thus the result set before a write would not be sorted by bucket function. With 
the absence of lenient ClusteredWriter this would make the test always fail for 
partitioned writes.
