Arun C Murthy commented on HADOOP-2501:
---------------------------------------

Sure... but we _do_ need more utils for SequenceFiles and I'm open to a discussion on how
we are going to structure them.

> 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:
> {noformat}
> $ bin/hadoop seq -info /user/joe/blah.seq
> $ bin/hadoop seq -head -n 10 /user/joe/blah.seq
> {noformat}
