Need better exception handling in RCFile tolerate corruptions mode
------------------------------------------------------------------

                 Key: HIVE-2660
                 URL: https://issues.apache.org/jira/browse/HIVE-2660
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
            Reporter: Ramkumar Vadali
            Assignee: Ramkumar Vadali
            Priority: Minor


The exception handling in nextKeyValueTolerateCorruptions treats IOException as follows:
 - if EOFException, corrupt, can be tolerated
 - If CheckSumException, corrupt, can be tolerated
 - else not a corruption, re-throw

But the compression code can also throw IOException in case of corruption, which will get
re-thrown in this case.

The correct way of handling IOException is:
 - if BlockMissingException, re-throw.
 - if not BlockMissingException -> corruption, can be tolerated
