title: Heartbeat lost in HDP cluster
body: <p>I am using 10 nodes HDP cluster, out of 10 one of the node was getting restarted within few hours, As suggested by Linux admin we had restaged that particular node. This node consists of Snamenode, one of the zookeeper server and hbase master.</p>
  
  <p>After restaging entire cluster went down, after restaging  of one node, the entire cluster should not get affected right? but instead of that I was getting heartbeat lost from all of the nodes except Master node.</p>
