             Summary: [ORC] column name matching while schema evolution should be case unaware.

                 Key: ORC-282
                 URL: https://issues.apache.org/jira/browse/ORC-282

          Issue Type: Bug
            Reporter: piyush mukati


in case of orc data reader schema passed by hive are all small cases and if the column name
stored in the file has any uppercase, it will return null values for those columns even if
the data is present in the file. 
Column name matching while schema evolution should be case unaware. 
we need to pass config for same from hive. the config in orc will be exposed by https://issues.apache.org/jira/browse/ORC-264
