  2. Execute the following API call to delete the current Metric Collector component:

    curl -u admin:admin -H "X-Requested-By:ambari" - i -X DELETE http://ambari.server:8080/api/v1/clusters/cluster.name/hosts/metrics.collector.hostname/host_components/METRICS_COLLECTOR

  3. Execute the following API call to add Metrics Collector to a new host:

    curl -u admin:admin -H "X-Requested-By:ambari" - i -X POST http://ambari.server:8080/api/v1/clusters/cluster.name/hosts/metrics.collector.hostname/host_components/METRICS_COLLECTOR

  4. In Ambari Web, go the page of the host on which you installed the new Metrics Collector and click Install the Metrics Collector.
