mmh3 not installed on Elastic MapReduce in AWS
You can use pip install mmh3 to install it.
I need to use mmh3 for hashing. However, when I run 
"python MultiwayJoin.py R.csv S.csv T.csv -r emr > output.txt" in terminal, it returned an error said that:
File "MultiwayJoin.py", line 5, in 
import mmh3
ImportError: No module named mmh3
