Description

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.
