Error: java.io.IOException: 400 - java.lang.NullPointerException, when broker start

[DakCo36]

System Status
Operating System: CentOS 7
Kernal Version: 3.10.0-514.el7.x86_64
Zookeeper: 3.4.9
Mesos: 1.3.0
mesoskafka: master or 0.10 (both occurred same error)

I kept receiving error when I start broker. It is ok to show broker list and add broker.

$ ./kafka-mesos.sh broker list
brokers:
  id: 0
  active: true
  state: starting
  resources: cpus:1.00, mem:2048, heap:1024, port:auto
  jvm-options: 
  failover: delay:1m, max-delay:10m

    offline-partitions-count: 0
    is-active-controller: 0

$ ./kafka-mesos.sh broker start 0
"Error: java.io.IOException: 400 - java.lang.NullPointerException"

This is my kafka-mesos.properties
mesos1, 2, 3 and master is hostname.
it is saved in /etc/hosts

debug=true
user=vagrant
storage=zk:/kafka-mesos 
master=zk://master:2181/mesos 
zk=mesos1:2181,mesos2:2181,mesos3:2181
api=http://master:7000

It is difficult to figure out that I did setup wrongly.
Could you help me?
