> URL: https://issues.apache.org/jira/browse/HIVE-511
> Project: Hadoop Hive
> Issue Type: Bug

> Reporter: Zheng Shao
> Fix For: 0.4.0
>
> Attachments: HIVE-511.1.patch, HIVE-511.2.patch

>
> The current DoubleWritable hashCode takes only the last 32 bits. This is a
> big problem because for small integer values like 1.0, 2.0, 15.0, the
> hashCode are all 0.
