> In some cases, we skip checking null. For example, the last statement in the
> following set of queries fails with NPE.
> {code:java}
> CREATE TABLE `store_sales` (`ss_item_sk` bigint);
> CREATE TABLE `household_demographics` (`hd_demo_sk` bigint);
> CREATE TABLE `item` (`i_item_sk` bigint);
> ALTER TABLE `store_sales` ADD CONSTRAINT `pk_ss` PRIMARY KEY (`ss_item_sk`)
> DISABLE NOVALIDATE RELY;
> ALTER TABLE `item` ADD CONSTRAINT `pk_i` PRIMARY KEY (`i_item_sk`) DISABLE
> NOVALIDATE RELY;
> ALTER TABLE `store_sales` ADD CONSTRAINT `ss_i` FOREIGN KEY (`ss_item_sk`)
> REFERENCES `item`(`i_item_sk`) DISABLE NOVALIDATE RELY;
> EXPLAIN
> SELECT i_item_sk

> WHERE ss_item_sk = i_item_sk{code}
> The NPE happens with HiveJoinConstraintsRule in the above case.
