How to set the KeyRange in an Hadoop+Cassandra job

Hi, 
I'm trying to set the KeyRange using the ConfigHelper API for a Cassandra 1.0.8 + Hadoop job.

The only API I see is 

public static void setInputRange(Configuration conf, String startToken, String endToken)

which allows me to set a key range specifying the startToken and endToken, but I'd like to set the starting and ending row key. How can I achieve that? 

Thanks,

Hey Filippo,

I think this question best belongs to the Cassandra user lists
(user@cassandra.apache.org) as it is pretty specific to its APIs and
implementation.
