> 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.
