@Michael Bronson This API will get you status of all components on all hosts in your cluster curl -u {ambari_username}:{ambari_password} -H "X-Requested-By:ambari" -i GET http://localhost:8080/api/v1/clusters/cl1/components?fields=host_components/HostRoles/state And if you need to find the status of individual component e.g for datanode; curl -u {ambari_username}:{ambari_password} -H "X-Requested-By:ambari" -i GET http://localhost:8080/api/v1/clusters/cl1/components/DATANODE?fields=host_components/HostRoles/state Hope this helps!

@Michael Bronson You can get the service components status from the "ServiceComponentInfo/state" parameter. 1. To get all components state in single API: API : <AMBARI_HOST>/api/v1/clusters/cl1/components?fields=ServiceComponentInfo/state E.g In the response you can find something like this when MR History server is stopped: "ServiceComponentInfo": {"cluster_name": "cl1","component_name": "HISTORYSERVER","service_name": "MAPREDUCE2","state": "INSTALLED"} 2. To get more info for individual component, You can use this API resource <AMBARI_HOST>/api/v1/clusters/cl1/services/MAPREDUCE2/components/HISTORYSERVER Hopefully this helps!

@vrathod, if you are looking for all supported OS for a stack for a given ambari release, you can try the getVersionDefinitions API with filters. E.g http://<AMBARI_HOST>:8080/api/v1/version_definitions?fields=VersionDefinition/stack_default,operating_systems/OperatingSystems/os_type,VersionDefinition/repository_version&VersionDefinition/show_available=true&VersionDefinition/stack_name=HDP Hope this helps!

@dbalasundaran You can try this APIs and programmatically find the diff between the configuration lists <AMBARI_HOST>/api/v1/clusters/cl1/configurations/service_config_versions?service_name=HDFS&group_name=<GROUP_NAME>&service_config_version.in(<VERSION_NUMBER>) E.g <AMBARI_HOST>/api/v1/clusters/cl1/configurations/service_config_versions?service_name=HDFS&group_name=mycg1&service_config_version.in(6)
<AMBARI_HOST>/api/v1/clusters/cl1/configurations/service_config_versions?service_name=HDFS&group_name=mycg1&service_config_version.in(7)

@nyadav To add to @krajguru's answer: You can use query parameter is_current=true to retrieve the latest configuration version in case you have multiple versions of configurations. E.g http://<Ambari-hostname>:8080/api/v1/clusters/<cluster-name>/configurations/service_config_versions?service_name=HDFS&is_current=true

Looks like we did some mistake while doing rpm cleanup. Copied oozie client jar to /usr/hdp/<version>/oozie/lib/ and it worked fine. Thanks!

@Romil Choksi You can prepare similar queries by identifying the fields defined using query parameter ?fields=* with most of the ambari APIs e.g <AMBARI_HOST>/api/v1/clusters/cl1/host_components?fields=*
