Re: custom format
Hi,

I found this while trying to see if such a FileFormat or Split already exists:
http://bitsofinfo.wordpress.com/2009/11/01/reading-fixed-length-width-input-record-reader-with-hadoop-mapreduce/

I have certainly not tried it myself, hence can't say if it is
current, etc. But maybe it'll help you in some way.

Thanks
Hemanth
