I could finally solve it by combining some of the steps mentioned above.

I first checked what is the value of `zookeeper.znode.parent` in HBase. I tried setting that same value in Ambari, but that did not work because some of the metrics processes were already running on that machine. So, i had to `ps -ef | grep metrics` and kill all of them as they were caching the `/hbase` value.

Watch the ambari metrics collector logs ( /var/log/ambari-metrics-collector/ambari-metrics-collector.log) while you do the below steps

其實，說白了，以下就是如何刪除Ambari中已有的服務!

步驟

　　Steps:0.

           tail -f /var/log/ambari-metrics-collector/ambari-metrics-collector.log  （這一也可以跳過，說白了就是檢視對應的ambari-metrics-collector的日誌而已）

　　　　   tail -f /var/log/ambari-metrics-collector/ambari-metrics-monitor.log  （這一也可以跳過，說白了就是檢視對應的ambari-metrics-monitor的日誌而已）

  Steps:1. Stop Ambari Metrics

　 　注意： 若是這步，關不掉Ambari  Metrics沒事，去步驟三吧！

　　Steps 2:. Kill all the metrics processes

ambari-metrics-monitor status

ambari-metrics-collector status

ambari-metrics-monitor stop

ambari-metrics-collector stop

kill -9 26554 

kill -9 46277

Steps:3 停止服務

curl -u admin:admin -H "X-Requested-By: ambari" -X PUT -d '{"RequestInfo": {"context":"Stop Service"},"Body":{"ServiceInfo":{"state":"INSTALLED"}}}' http://192.168.80.144:8080/api/v1/clusters/hdpCluster/services/AMBARI_METRICS

注意：

192.168.80.144是我這臺機器ambari01（即搭建了ambari）的ip，你注意改為你自己的！

hdpCluster是我叢集的名字，你注意改為你自己的！

AMBARI_METRICS這裡是停止該服務並要從ambari裡刪除它。

Steps:4 刪除服務（快速立即執行）

curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE http://192.168.80.144:8080/api/v1/clusters/hdpCluster/services/AMBARI_METRICS

注意：

192.168.80.144是我這臺機器ambari01（即搭建了ambari）的ip，你注意改為你自己的！

hdpCluster是我叢集的名字，你注意改為你自己的！

AMBARI_METRICS這裡是停止該服務並要從ambari裡刪除它。

Steps:4   Refresh Ambari UI

Steps:5  Add Service

Steps:6 . Select Ambari Metrics

7. In the configuration screen, make sure to set the value of `zookeeper.znode.parent` to what is configured in the HBase service. By default in Ambari Metrics it is set to empty value.

8. Deploy

　　如果依然，上述的方法做了之後，出現，如下的情況，繼續解決:

　　最終是一定可以解決，Ambari Metrics無法啟動的問題。
