我在S1（服务器1）上有td-agent，在S2上我有zookeeper和kafka，在S3我有太多的zookeeper和kafka， td-agent的配置是
type ruby_kafka zookeepers S2:2181,S3:2181 default_topic topic1
但当S2在S1上关闭我的td-agent时，不要在S3上向zookeeper发送数据
td-agent的状态为[FAILED] 2017-03-28 11:05:10 +0000 [error]: fluent/supervisor.rb:373:rescue in main_process: config error file="/etc/td-agent/td-agent.conf" error="Broker has not been set."
