Implement utility-tools for working with SequenceFiles
------------------------------------------------------
Key: HADOOP-2501
URL: https://issues.apache.org/jira/browse/HADOOP-2501
Project: Hadoop
Issue Type: New Feature
Components: io
Reporter: Arun C Murthy
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}
