Rajesh Balamohan commented on HIVE-7557:
----------------------------------------
Matt - processOp (serialization bug) is due to the wrong projection which is
not related to ReduceRecordProcessor. In dynpart_sort_opt_vectorization.q ,
projected fields should be just 4. But when the data lands up in
VectorizedOrcSerde, it has 5 columns. This needs to be fixed in other layer.
ReduceRecordProcessor.processVectors when trying to call toString on the batch,
is harmless at this time. I will fix that and upload the patch asap.
> When reduce is vectorized, dynpart_sort_opt_vectorization.q under Tez fails
