Subject Re: HBase cluster health java api
Date Thu, 19 Jan 2017 13:24:58 GMT
You can use the following method from HBaseAdmin:

  public ClusterStatus getClusterStatus() throws IOException {

where ClusterStatus has getter for retrieving live server count:

  public int getServersSize() {

and getter for retrieving dead server count:

  public int getDeadServers() {


FYI
