This should be doable by either the Java or REST APIs, as well as the CLI
(in fact, the CLI uses the Java API which uses the REST API). There are
obviously some differences in formatting and usage though.
To get the list of WorkflowActions form a Workflow Job ID in the Java
Client API, you can do:
List<WorkflowAction> = OozieClient.getJobInfo(String JobId).getActions();
Here is the Javadoc for the Client API:
http://archive.cloudera.com/cdh4/cdh/4/oozie/client/apidocs/index.htmlThe equivalent call for the REST API is shown here:
http://archive.cloudera.com/cdh4/cdh/4/oozie/WebServicesAPI.html#Job_InformationThe equivalent call for the CLI is shown here (though you’d have to do a
bunch of parsing to get specific info as its designed to be human-readable):

Hi,
Thanks for your reply.
I checked the Oozie client API. I couldn't find an API which will provide
me with list of WorkflowActions, when I input the workflow id.
Could you please point me to that API ?
Thanks.

Notice that is it non trivial to report an overall progress of the
workflow as some actions won't necessarily be ran. Oozie does not give an
indicator out of the box.

Thanks for the reply.
I'm currently using Java Oozie Client. All I have is the access to
workflow Id.
But to be able to get the job progress through #mapprogress(), or
#reduceprogress() methods of JobClient, I would require the actual job id
(not the workflow id)
Is there any API that can give me actual hadoop job id by inputting
oozie workflow id ?

Take a look at
http://oozie.apache.org/docs/3.3.2/WebServicesAPI.htmlfor documentation on Oozie's web service layer. Here is how Hue calculates
progress of a workflow:
https://github.com/cloudera/hue/blob/master/desktop/libs/liboozie/src/liboozie/types.py#L258.
Hue actually updates its UI dynamically over AJAX and a REST/JSON API.
You might able to hook into that? It should be 'GET
/oozie/list_oozie_workflow/<job id>?format=json'.

Hi,
I'm currently using Oozie workflow to trigger a mapreduce job.
Does Hue/Oozie provide an API or a web service to be able to track
the progress of the workflow in terms of percentage that is shown on it's
UI ?
Like 33% complete ... and so on.
Any help is appreciated.
