------------------------------------
Summary: 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: Improvement
Components: docs
Affects Versions: trunk
Reporter: Robert Kanter
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:
