Chao commented on HIVE-8486:
----------------------------
OK, I enabled them and re-deployed the code on the cluster. But, even though
the number of bytes is much bigger now, it is still less than the default
bytes-per-reducer, which is 1G. So, the estimation still only gives one reducer
as result.
