-----------------------------------
Summary: Scramble HashPartitioner hashes
Key: FLINK-3422
URL: https://issues.apache.org/jira/browse/FLINK-3422
Project: Flink
Issue Type: Improvement
Components: Streaming
Affects Versions: 0.10.2
Reporter: Stephan Ewen
Priority: Critical
Fix For: 1.0.0
The {{HashPartitioner}} used by the streaming API does not apply any hash
scrambling against bad user hash functions.
We should apply a murmor or jenkins hash on top of the hash code, similar as in
the {{DataSet}} API.
