> Result of HashFunction.hash() contains all identical values

> Key: HADOOP-2365
> URL: https://issues.apache.org/jira/browse/HADOOP-2365
> Project: Hadoop
> Issue Type: Bug
> Components: contrib/hbase
> Affects Versions: 0.16.0
> Reporter: Andrzej Bialecki
> Assignee: Jim Kellerman
> Fix For: 0.16.0
>
> Attachments: hash-v1.patch, patch.txt
>
>
> There is a small bug in HashFunction:112 - initvalue should be changed
> between the loop iterations in order to spread the hash values over the whole
> allowed range. Instead the current code uses a fixed initvalue = 0, which
> gives all identical hash values in the result array. As a result,
> BloomFilter-s have extremely high rate of false positives.
