      Description

      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
      
      2019-06-11 19:46:02,731 DEBUG [timeline] timeline.HadoopTimelineMetricsSink: Trying to find live collector host from : [c2111-node3.hdp.com,c2111-node2.hdp.com]
      2019-06-11 19:46:02,731 DEBUG [timeline] timeline.HadoopTimelineMetricsSink: Requesting live collector nodes : http://c2111-node3.hdp.com,c2111-node2.hdp.com:6188/ws/v1/timeline/metrics/livenodes

      In HadoopTimelineMetricsSink.java

          collectorHosts = parseHostsStringArrayIntoCollection(conf.getStringArray(COLLECTOR_HOSTS_PROPERTY));
      

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