submitting to multiple masters

[James King]

I have multiple masters running and I'm trying to submit an application
using

spark-1.3.0-bin-hadoop2.4/bin/spark-submit

with this config (i.e. a comma separated list of master urls)

                      --master spark://master01:7077,spark://master02:7077


But getting this exception

Exception in thread "main" org.apache.spark.SparkException: Invalid master
URL: spark://spark://master02:7077


What am I doing wrong?

Many Thanks
