> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Affects Versions: 1.0.1

>
> HIVE-11983 adds ObjectInspectorUtils.getBucketHashCode() and
> getBucketNumber().
> There are several (at least) places in Hive that perform this computation:
> # ReduceSinkOperator.computeBucketNumber
> # ReduceSinkOperator.computeHashCode
> # BucketIdResolverImpl - only in 2.0.0 ASF line
> # FileSinkOperator.findWriterOffset
> # GenericUDFHash
> Should refactor it and make sure they all call methods from
> ObjectInspectorUtils.
