Chao Sun updated SPARK-32703:
-----------------------------
Description: Parquet vectorized reader still uses the old API for
{{filterRowGroups}} and only filters on statistics. It should switch to the new
API and do dictionary filtering as well. (was: Dictionary filtering was
disabled in SPARK-26677 due to a Parquet bug in 1.10.0 but was fixed 1.10.1.
Since we've upgraded to the latter version, we should consider to re-enable
this feature.)
