    Description

      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.
