    Description

      It would be nice to implement a bunch of utilities to work with SequenceFiles:

      • info (print-out header information such as key/value types, compression type/codec etc.)
      • cat
      • head/tail
      • merge multiple seq-files into one
      • ...

      I'd imagine this would look like:

      $ bin/hadoop seq -info /user/joe/blah.seq
$ bin/hadoop seq -head -n 10 /user/joe/blah.seq
