Subject [jira] [Created] (ORC-291) Add input format for stitching together multiple files

---------------------------------

             Summary: Add input format for stitching together multiple files 
                 Key: ORC-291
                 URL: https://issues.apache.org/jira/browse/ORC-291
             Project: ORC
          Issue Type: Improvement
            Reporter: Owen O'Malley


It would be useful to have the ability to have an InputFormat that stitches together multiple
files where the files have a 1:1 relationship for rows. If the column name has appeared previously,
its value will be used instead of the original value. If the column name is new, it will be
appended on to the row.

This will allow simple cases of appending or updating fields without re-writing the file until
later.
