[jira] [Created] (HIVE-5876) Split elimination in ORC breaks for partitioned tables

             Summary: Split elimination in ORC breaks for partitioned tables
                 Key: HIVE-5876
                 URL: https://issues.apache.org/jira/browse/HIVE-5876
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.13.0
            Reporter: Prasanth J
            Assignee: Prasanth J


HIVE-5632 eliminates ORC stripes from split computation that do not satisfy SARG condition. SARG expression can also refer to partition columns. But partition column will not be contained in the column names list in ORC file. This was causing ArrayIndexOutOfBoundException in split elimination logic when used with partitioned tables. The fix is to ignore evaluation of partition column expressions in split elimination.
