Robert Kanter reassigned OOZIE-1696:
------------------------------------
Assignee: Robert Kanter
> Document how to get the action conf in the Java action
> ------------------------------------------------------
>
> Key: OOZIE-1696
> URL: https://issues.apache.org/jira/browse/OOZIE-1696
> Project: Oozie
> Issue Type: Sub-task
> Components: docs
> Affects Versions: trunk
> Reporter: Robert Kanter
> Assignee: Robert Kanter
> Labels: newbie
>
> The Java action doesn't get a lot of the "magic" that we do in the other
> actions, so things don't always behave right for users using the Java action
> to launch MapReduce jobs. We've seen some confusion where these jobs were
> picking up the mapred-default properties and not working because of it. It
> would be great if we could document how to use the job conf prepared by
> Oozie, which includes the proper mapred-site.xml (and other site files), plus
> anything in the {{<configuration>}} section of the Java action.
> Basically, they just need to create their job conf with something like this
> (taken from MapReduceMain.java):
> {code:java}
> Configuration actionConf = new Configuration(false);
> actionConf.addResource(new Path("file:///",
> System.getProperty("oozie.action.conf.xml")));
> {code}
> We can put it next to the already documented snippet about the delegation
> token propagation here:
> http://oozie.apache.org/docs/4.0.0/WorkflowFunctionalSpec.html#a3.2.7_Java_Action
