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

             Summary: An implementation of RecordReader/FileInputFormat for generic binary
data
                 Key: MAPREDUCE-6461
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6461
             Project: Hadoop Map/Reduce
          Issue Type: Wish
          Components: mrv2
            Reporter: Dustin Cote
            Priority: Minor


It would be nice to have a RecordReader implementation designed for binary data for ETL processing
(especially for mainframe encodings like EBCDIC).  Currently, we have: http://hadoop.apache.org/docs/current/api/org/apache/hadoop/mapred/FixedLengthInputFormat.html

This is great for fix length fields, but it would be even better if we could delimit records
by a byte string dynamically.
