The ambari-metrics-collector log showing the below message only:

ambari-metrics-collector.log :

2017-06-06 05:56:48,415 WARN org.apache.hadoop.yarn.server.applicationhistoryservice.metrics.timeline.query.DefaultPhoenixDataSource: Unable to connect to HBase store using Phoenix.
org.apache.phoenix.schema.TableNotFoundException: ERROR 1012 (42M03): Table undefined. tableName=SYSTEM.CATALOG

	at org.apache.phoenix.query.ConnectionQueryServicesImpl.checkClientServerCompatibility(ConnectionQueryServicesImpl.java:939

So, as asked earlier; did you followed all the steps defined in article [1]. If yes and still facing issue then please attach the hbase-ams-master.log file from location of "/var/log/ambari-metrics-collector/hbase-ams-master-<hostname -f>.log" and also share the '/etc/ambari-metrics-monitor/conf/metric_monitor.ini" file from any host where ambari-metrics-monitor is running.

Also, Can you try to telnet to ambari-metrics-collector from any host using cmd : telnet c2m.xdata.com 6188

Hi,

Today i deployed Hortonworks cluster in AWS cloud. Even i am facing same issue while starting AMS collector. Please find the log files for the same.

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

netstat -tulpn | grep 6188

No result. So AMS is down.
