title: Apache kafka lot of WARN log show Unexpected error
body: <p>I was running Kafka with 2 borker for cluster.</p>
  
  <p>But I keep getting the WARN log.</p>
  
  <p>I checked all my systems and there was no host using IP 10.8.7.1.</p>
  
  <p>By the way, there was more IPs looks like from zookeeper or broker ?</p>
  
  <p>If I shotdown on of Kafka, the WARNING log will be less</p>
  
  <p>I am not familiar with Kafka and zookeeper, just getting starting and study</p>
  
  <p>Any ideas?</p>
  
  <p>Kafka version: 1.0.1</p>
  
  <p>WARN log similar as below(get this kind of log about 10 secs), </p>
