Review request for hive and Eugene Koifman.
Bugs: HIVE-17917
https://issues.apache.org/jira/browse/HIVE-17917
Repository: hive-git
Description
-------
VectorizedOrcAcidRowBatchReader.computeOffsetAndBucket optimization()
computation is currently (after HIVE-17458) is done once per split. It could
instead be done once per file (since the result is the same for each split of
the same file) and passed along in OrcSplit
