> BucketingSortingReduceSinkOptimizer makes 
> insert into AcidTable select * from otherAcidTable
> use BucketizedHiveInputFormat which bypasses ORC merge logic on read and tries to send
bucket files (rather than table dir) down to OrcInputFormat.
> (this is true only if both AcidTable and otherAcidTable are bucketed the same way). 
Then ORC dies.
