HashFunction inadvertently destroys some randomness
----------------------------------------------------
Key: HADOOP-5079
URL: https://issues.apache.org/jira/browse/HADOOP-5079
Project: Hadoop Core
Issue Type: Bug
Components: util
Reporter: Jonathan Ellis
Attachments: hadoop-core-hash.patch
HashFunction.hash restricts initval for the next hash to the [0, maxValue)
range of the hash indexes returned. This is suboptimal, particularly for larger
nbHash and smaller maxValue. Rather we should first set initval, then restrict
the range for the result assignment.
