Marathon exited with status 1

I am installing mesosphere on ubuntu 16.04 xenial .zookeeper and mesos-master and mesos-slave are running fine ,while starting marathon I am getting this issue . Required option 'master' not found .I have created folder in /etc/marathon/conf .These are the steps I am following for marathon .

sudo mkdir -p /etc/marathon/conf
sudo cp /etc/mesos-master/hostname /etc/marathon/conf
sudo cp /etc/mesos/zk /etc/marathon/conf/master
sudo cp /etc/marathon/conf/master /etc/marathon/conf/zk
sudo nano /etc/marathon/conf/zk ,edit mesos to marathon in the end .

I am attaching the whole logs here,

Solution

Breaking Changes / Packaging standardized

We now publish more normalized packages that attempt to follow Linux Standard Base Guidelines and use sbt-native-packager to achieve this. As a result of this and the many historic ways of passing options into marathon, we will only read /etc/default/marathon when starting up. This file, like /etc/sysconfig/marathon, has all marathon command line options as "MARATHON_XXX=YYY" which will translate to --xx=yyy. We no longer support /etc/marathon/conf which was a set of files that would get translated into command line arguments. In addition, we no longer assume that if there is no zk/master argument passed in, then both are running on localhost.

Try to keep config in the environment.

cat << EOF > /etc/default/marathon
MARATHON_MASTER=zk://127.0.0.1:2181/mesos
MARATHON_ZK=zk://127.0.0.1:2181/marathon
EOF

Remember to replace 127.0.0.1:2181 with proper Zookeeper location.
