> Key: HADOOP-5079
> URL: https://issues.apache.org/jira/browse/HADOOP-5079
> Project: Hadoop Core
> Issue Type: Bug
> Components: util

> 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.
