Converting to sequence file in mahout

[jamal sasha]

Hi,
   I have data where each row is comma seperated vector...
And these are bunch of text files...like
0.123,01433,0.932
0.129,0.932,0.123
And I want to run's mahout rowIdSimilarity module on it.. butI am guessing
the input requirement is different.
How do I convert this csv vectors into format consumed by mahout
rowIdSimilarity module?
Thanks
