How to automate configuration changes to non default Ambari config group?

abajwa — Wed, 30 Sep 2015 11:01:44 GMT

/var/lib/ambari-server/resources/scripts/configs.sh is a great way to automate config changes, but seems it only supports the 'Default' config group. Is there a clean way to make changes to other config groups via API?

Yes you can use APIs. Sample:

A PUT call at http://ambari.host:8080/api/v1/clusters/c1/config_groups/2

with payload:

[{"ConfigGroup":{"id":2,"cluster_name":"c1","group_name":"A config group","tag":"HDFS","description":"A config group","hosts":[{"host_name":"host1"}],"service_config_version_note":"change","desired_configs":[{"type":"hdfs-site","tag":"version1443587493807","properties":{"dfs.replication":"2","dfs.datanode.du.reserved":"1073741822"}}]}}]

will modify the config group. A POST to http://ambari.host:8080/api/v1/clusters/c1/config_groups would have created a new config group.

Thanks @smohanty@hortonworks.com. Is it correct to say that we need to pass in previously configured properties as well as new properties together to the POST? (to avoid removal of existing properties)
