title: How do we know replication status in elasticsearch?
body: <p>I have set up elastic-search cluster with a single node(node1) and indexed data. After indexing is complete on the node1, another node(node2) is added to the cluster. Now I have configured the number of replicas to 1. The replication is completed successfully. But how do we know that replication is complete? Is there any API available which returns the replication status like In progress, complete..  . </p>
  
  <p>My requirement is that I should be notified when the replication is complete.</p>
