Panagiotis Garefalakis updated HIVE-25103:
------------------------------------------
Description:
HIVE-16222 introduced row.serde.inputformat.excludes setting to disable
row.serde for specific NON-Vectorized formats.
Since MapredParquetInputFormat is currently natively vectorized it should be
removed from that list.
Even when hive.vectorized.use.vectorized.input.format is DISABLED
Vectorizer will not vectorize in row deserialize mode if the input format has
is natively Vectorized so it is safe to remove.
There is a precedence/order to control vectorization:
1. hive.vectorized.use.vectorized.input.format
2. hive.vectorized.use.vector.serde.deserialize
3. hive.vectorized.use.row.serde.deserialize
