[jira] [Created] (HIVE-6562) Protection from exceptions in ORC predicate evaluation

Prasanth J created HIVE-6562:
--------------------------------

             Summary: Protection from exceptions in ORC predicate evaluation
                 Key: HIVE-6562
                 URL: https://issues.apache.org/jira/browse/HIVE-6562
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.13.0
            Reporter: Prasanth J
            Assignee: Prasanth J
         Attachments: HIVE-6562.1.patch

ORC evaluates predicate expressions to select row groups that satisfy predicate condition. There can be exceptions (mostly ClassCastException) when data types of predicate constant and min/max values are different. 
To avoid this patch catches any such exception and provides a default behaviour i.e; selecting the row group.
