I have used the '9001' port for another application,so i want to change the JobTracker port.

I changed the parameter 'jt.port' in the warden.conf,and i restarted the service mapr-warden,but the log shows :

"2013-11-29 21:32:59,835 FATAL org.apache.hadoop.mapred.JobTracker: java.net.BindException: Problem binding to /0.0.0.0:9001 : Address already in use"

so i want to know how to deal with the question.
