Ambari2.5.3卸载smartsense

第一步，确定SmartSence服务均已关闭

 curl -u admin:$PASSWORD -i -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo": {"context" :"Stop SmartSense via REST"}, "Body": {"ServiceInfo": {"state": "INSTALLED"}}}' http://AMBARI_SERVER_HOST:8080/api/v1/clusters/CLUSTER_NAME/services/SMARTSENSE

第二步，卸载SmartSense组件

  curl -u admin:$PASSWORD -i -H 'X-Requested-By: ambari' -X POST -d '{"RequestInfo": {"context" :"Uninstall SmartSense via REST", "command":"Uninstall"}, "Requests/resource_filters":[{"hosts":"comma separated host names", "service_name":"SMARTSENSE", "component_name":"HST_AGENT"}]}' http://AMBARI_SERVER_HOST:8080/api/v1/clusters/CLUSTER_NAME/requests

第三步，从Ambari中卸载掉SmartSense服务

 curl -u admin:$PASSWORD -H 'X-Requested-By: ambari' -X DELETE http://AMBARI_SERVER_HOST:8080/api/v1/clusters/CLUSTER_NAME/services/SMARTSENSE

第四步，重起Ambari使更改生效

 ambari-server restart

　　注释：admin为用户名，不用更改；￥PASSWORD为admin的密码，修改成自己admin的密码；AMBARI_SERVER_HOST是ambari-server所在主机的IP或者域名，要修改成自己ambari-server的；CLUSTER_NAME是ambari上安装的集群的名字，即要卸载哪个集群上的SmartSense就写哪个集群的名字。
