> The store_sales table is partitioned on ss_sold_date_sk, which is also used in a join
clause. The join clause should add a filter “filterExpr: ss_sold_date_sk is not null”,
which should get pushed the MetaStore when fetching the stats. Currently this is not done
in CBO planning, which results in the stats from __HIVE_DEFAULT_PARTITION__ to be fetched
and considered in the optimization phase. In particular, this increases the NDV for the join
columns and may result in wrong planning.
> Including HiveJoinAddNotNullRule in the optimization phase solves this issue.
