Exception when passing key in hashed.py

[siniG]

Hi,
I receive the following error when trying to send a message using HashedPartitioner with Murmur2 function "TypeError: string argument without an encoding".

This happens on line #53 at the beginning of murmur2 method as bytearray is expecting encoding type which is not given.

Convert key to a bytearray

if not isinstance(key, bytearray):
    data = bytearray(str(key))

[mutability]

Together with #428 this makes Murmur2Partitioner unusable in python 3: you can't pass a bytearray, but you can't pass a non-bytearray either.

fixed in PR #439
