---------------------------------------------

             Summary: Ambari metrics HA does not work in 2.7.3 for Hbase/any /services
                 Key: AMBARI-25301
                 URL: https://issues.apache.org/jira/browse/AMBARI-25301
             Project: Ambari
          Issue Type: Bug
          Components: ambari-metrics
    Affects Versions: 2.7.3
            Reporter: amarnath reddy pappu


Steps to reproduce:
-------------------------
1. Install Ambari 2.7.3 and HDP3.1 cluster.
2. Add Ambari metrics service.
3. From host page, add another ambari metrics collector.
4. Hbase would not be able to connect to collector.

Root cause:
hadop-sink is not able to spit these below hosts and end of with bad URL.

hbase.sink.timeline.collector.hosts=c2111-node3.hdp.com,c2111-node2.hdp.com

In HadoopTimelineMetricsSink.java 

{code:java}
    collectorHosts = parseHostsStringArrayIntoCollection(conf.getStringArray(COLLECTOR_HOSTS_PROPERTY));
{code}

conf.getStringArray(COLLECTOR_HOSTS_PROPERTY) is not actually returning the String array.
