Vihang Karajgaonkar commented on HIVE-14171:
--------------------------------------------
AFAIK {{hive.vectorized.use.row.serde.deserialize}} is not supported for
Parquet. Does it fail if you set to false as well? Many fixes for Parquet
vectorized reader went in 2.3.0. So it would be good to check using 2.3.0 if
its possible.
