Description

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 :
