Teddy Choi commented on HIVE-17164:
-----------------------------------
The patch looks good, but some tests are failed.
llap/vector_ptf_part_simple.q.out is failed because of different fractions.
Also vector_windowing_expressions.q.out for TestCliDriver needs to be updated,
too.
> Vectorization: Support PTF (Part 2: Unbounded Support-- Turn ON by default)

> Add hive.vectorized.ptf.max.memory.buffering.batch.count to specify the
> maximum number of vectorized row batch to buffer in memory before spilling to
> disk.
> Add hive.vectorized.testing.reducer.batch.size parameter to have the Tez
> Reducer make small batches for making a lot of key group batches that cause
> memory buffering and disk storage backing.
