> Add disk storage backing.  Turn hive.vectorized.execution.ptf.enabled 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.
