@Michael Bronson, You can use the below curl call to get the info curl -u {ambari-username}:{ambari-password} -H "X-Requested-By: ambari" -X GET http://{ambari-host}:{ambari-port}/api/v1/clusters/{clustername}/hosts/{host-name}/host_components?fields=HostRoles/state Sample response: { "href": "http://10.10.1.1:8080/api/v1/clusters/cl1/hosts/master03/host_components?fields=HostRoles/state", "items": [ { "href": "http://10.10.1.1:8080/api/v1/clusters/cl1/hosts/master03/host_components/ACCUMULO_CLIENT", "HostRoles": { "cluster_name": "cl1", "component_name": "ACCUMULO_CLIENT", "host_name": "master03", "state": "INSTALLED" }, "host": { "href": "http://10.10.1.1:8080/api/v1/clusters/cl1/hosts/master03" } }, { "href": "http://10.10.1.1:8080/api/v1/clusters/cl1/hosts/master03/host_components/APP_TIMELINE_SERVER", "HostRoles": { "cluster_name": "cl1", "component_name": "APP_TIMELINE_SERVER", "host_name": "master03", "state": "STARTED" }, "host": { "href": "http://10.10.1.1:8080/api/v1/clusters/cl1/hosts/master03" } } ] } Thanks, Aditya ...

@Michael Bronson, I'm not sure why the above API is returning different status. It may be a bug. You can use this API to get the correct status curl -u {ambari-username}:{ambari-password} -H "X-Requested-By: ambari" -X GET http://{ambari-host}:{ambari-port}/api/v1/clusters/{clustername}/hosts/{host-name}/host_components/APP_TIMELINE_SERVER?fields=HostRoles/state Replace the place holders. {host-name} should be replaced with the hostname of the APP TIMELINE SERVER.

@yassine sihi, There is a json file (role_command_order.json) which specifies the dependencies of starting/stopping the services. If there is no dependency then the start/stop of services between hosts will run in parallel. You can find the files by running the command in ambari server node find /var/lib/ambari-server/resources -iname role_command_order.json Files inside common-services(/var/lib/ambari-server/resources/common-services) specify the dependency at a service level whereas files inside (/var/lib/ambari-server/resources/stacks) specify overall dependencies at stack level. Consider this sample line in one of the file "LIVY_SERVER-START" : ["NAMENODE-START", "DATANODE-START", "APP_TIMELINE_SERVER-START"] This specifies that livy server start is dependent on namenode, datanode and app timeline server start. Hope this helps 🙂 Thanks, Aditya ... View more

@Sonia Garudi, From HDP 2.6.4, due to licensing issues mysql was removed. All the GPL licensed components will be removed from now. If you are using mysql for hive then you should install it by yourself. Thanks, Aditya ... View more
