While reading data from Cassandra in map-reduce, I am getting 
"InvalidRequestException(why:Start token sorts after end token)"

Below is the code snippet that I used and the entire stack trace.
(I am using Cassandra 1.2.0 and hadoop 0.20.2)
Can you point out the issue here ?

Code snippet:
    SlicePredicate predicate = new SlicePredicate();

     SliceRange sliceRange = new SliceRange();
     sliceRange.start = ByteBuffer.wrap(("1".getBytes()));
     sliceRange.finish = ByteBuffer.wrap(("1000000".getBytes()));
     sliceRange.reversed = false;
     //    predicate.slice_range = sliceRange;

     List<ByteBuffer> colNames = new ArrayList<ByteBuffer>();
     colNames.add(ByteBuffer.wrap("url".getBytes()));
     colNames.add(ByteBuffer.wrap("Parent".getBytes()));
     predicate.column_names = colNames;

     ConfigHelper.setInputSlicePredicate(job.getConfiguration(), predicate);

Full stack trace:
java.lang.RuntimeException: InvalidRequestException(why:Start token sorts after 
end token)

tried out on a single node, but the cassandra-cli way showed no 
endpoint details either
