> The vectorized plan generation finds the list of partitioning columns from
> pruned-partition-list using table scan operator. In some cases the list is
> coming as null. TPCDS query 27 can reproduce this issue if the store_sales
> table is partitioned on ss_store_sk. The exception stacktrace is :
> {code}
> Caused by: java.lang.NullPointerException
