Subject Splitting map and reduce
Date Wed, 25 Jun 2014 13:07:14 GMT
Hi,

This is my first mail to this user group. I hope that the email is well
formed and enables me to learn a great deal about Hadoop.

I have to carry out sequence alignment using Hadoop with the aid of a
critical subsequence. A potential critical subsequence is derived from the
longest unique subsequence in a sequence. A valid critical subsequence must
exist in one or more sequences.

I have run a concordance with a line splitter and have able to get "Map
input records=10² Which leads me to believe I can assess each sequence
independently.

I was hoping to get 10 reduce outputs but I only got one. Is there a way to
split the reduce output in the same way that I can split the map input.

Thanks in advance, 
Regards,

Chris MacKenzie
