updating oozie-site.xml via REST api

doronve — Fri, 16 Sep 2022 09:28:44 GMT

Can I update oozie-site.xml using REST api?

We added our own external function to oozie.

After each installation we need to go manually and change things in oozie via the CM web interface:

i'd like to be able to do this via scripting of any kind.

Thanks

Hi Doron,

All configuration properties are in the CM REST API.

See the tutorials about using our rest API here:
http://cloudera.github.io/cm_api/

These include tutorials about how to read and set config, such as:
http://cloudera.github.io/cm_api/docs/python-client/#configuring-services-and-roles

Using the rest endpoint for configs directly is documented on the page you linked. There's a different endpoint for each concept (host, service, role config group, role, etc). The one you'd want for Oozie Server role config group is:
http://cloudera.github.io/cm_api/apidocs/v10/path__clusters_-clusterName-_services_-serviceName-_roleConfigGroups_-roleConfigGroupName-_config.html

Theses configs have the keys oozie_config_safety_valve, oozie_executor_extension_classes, and oozie_workflow_extension_schemas.

The most reliable way to identify config keys is to query your live CM via the API, using the option ?view=FULL, as described in the first link above. Documentation for config values is also available here (assuming CDH5.4, you can click other links for other versions):
http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cm_props_cdh540_oozie.html

Thanks,
Darren
