--------------------------------
Summary: ORC split elimination can cause NPE when column
statistics is null
Key: HIVE-8778
URL: https://issues.apache.org/jira/browse/HIVE-8778
Project: Hive
Issue Type: Bug
Affects Versions: 0.14.0
Reporter: Prasanth J
Assignee: Prasanth J
Priority: Critical
Fix For: 0.14.0
Row group elimination has protection for NULL statistics values in
RecordReaderImpl.evaluatePredicate() which then calls evaluatePredicateRange().
But split elimination directly calls evaluatePredicateRange() without NULL
protection. This can lead to NullPointerException when a column is NULL in
entire stripe.
