Kafka MirrorMaker is not starting

[#1]

I installed kafka 0.9 on my existing CDH 5.5.2 cluster. I choose 1 node as Kafka broker and 4 nodes as Kafka MirrorMakers. Kafka Broker has been started sucessfully, but MirrorMakers are not starting. i couldn't find any error in kafka log file, it's just showing like below
