Jonathan Ellis commented on CASSANDRA-3772:
-------------------------------------------
bq. I looked up guava source code but I saw no way to "reset", so I guess the
above is the only thing you could do
It looks like you're right:
http://code.google.com/p/guava-libraries/source/browse/guava/src/com/google/common/hash/MessageDigestHashFunction.java
So using the standalone MH3 library is probably the way to go.

> MD5 is a relatively heavyweight hash to use when we don't need cryptographic
> qualities, just a good output distribution. Let's see how much overhead we
