Remus Rusanu commented on HIVE-5653:
------------------------------------
Cause is the VectorReduceSinkOperator, which does not initialize the tagBytes
from the conf during initializeOp. This results in reduce side
ExecReducer.reduce reading all keys as tag (==alias) 0. The reduce join
operator sees all data in one side, nothing on the other, no rows match.
> Vectorized Shuffle Join produces incorrect results

> Vectorized shuffle join should work out-of-the-box, but it produces empty
> result set. Investigating.
