@Jay SenSharma I try it and it works fine. It should be: curl -u ${ambari_user_name}:${ambari_user_pass} -H "X-Requested-By: ambari"-d '{"RequestInfo":{"context":"Starting Flume agent","flume_handler":"agent","operation_level": {"level":"HOST_COMPONENT","cluster_name":"${CLUSTER_NAME}","service_name":"FLUME","host_name":"${hostname_of_new_flume_agent}"}},"Body":{"HostRoles":{"state":"STARTED"}}}'-X PUT "http://${AMBARI_HOST}:8080/api/v1/clusters/${CLUSTER_NAME}/hosts/${hostname_of_new_flume_agent}/host_components/FLUME_HANDLER" And now if I want do add a new agent ,I must change the configure on the ambari web ui ,then call the ambari server api above. Why not make it more easy??
