Radim Kolar commented on HADOOP-9088:
-------------------------------------
to improve hashing. WritableComparator hash is weak (used by
binarypartitioner), HashPartitioner sucks even more (using object.hashcode), i
will add TextPartitioner using murmur3, it have good distribution of results.
> Add Murmur3 hash
