Distcp starting only 1 mapper at a time.

I am trying to to distcp lots of small files from on HDFS to another. But
even after specifying number of mappers = 200 by option -m 200 distcp is
starting only 1 map job.
Average file size is less than 100mb.

Is there any way to start more mappers.
I have tried -m option.

Thanks,
