omalley requested code review of "HIVE-5580 [jira] push down predicates with an and-operator between non-SARGable predicates will get NPE".

Reviewers: JIRA

HIVE-5580

When all of the predicates in an AND-operator in a SARG expression get removed by the SARG builder, evaluation can end up with a NPE. Sub-expressions are typically removed from AND-operators because they aren't SARGable.
