[~tejasp] I can see HiveHash merged but never used. Seems the using of 
spark/hive hash is still under discussion, is there any update on this topic?

> Spark internally uses Murmur3Hash for partitioning. This is different from 
> the one used by Hive. For queries which use bucketing this leads to different 
> results if one tries the same query on both engines. For us, we want users to 
> have backward compatibility to that one can switch parts of applications 
> across the engines without observing regressions.
