我是Mesos和Marathon服务的新手。我根据www.digitalocean.com设置了3个主服务器和3个从服务器。在主服务器和从服务器中配置。最后我完成了Mesos，Marathon，Zookeeper和Chronos的设置。 Mesos能够以5050上市，Marathon是8080和Chronos 4400.几个小时之后，我的Marthon实例显示出错误503
HTTP ERROR: 503
Problem accessing /. Reason:
Could not determine the current leader

但是mesos工作正常。每次我遇到这个问题，如果我重新启动马拉松服务和动物园管理员服务它的工作正常。
