Alejandro,
Thanks. So are the configuration properties passed to the Java class in the
workflow supposed to be in an xml file specified by 'oozie.action.conf.xml '?
And that xml file will exist on the HDFS when the Java class runs?
If so, in my Java class did:
String oozieProps = System.getProperty("oozie.action.conf.xml");
It did return a path to an XML, but when it tried to open/read the file, it got
an IO exception that it did not exist.
Steve

Subject: Re: question on how Java class from workflow action reads properties
Hi Steve,
>From Mona's Java Cookbook doc which is not live yet:
-----
Within your Java Main class, you can query for the following system
properties pertaining to your Oozie job.
* oozie.job.id : Workflow ID
* oozie.action.id : Action ID
* oozie.action.conf.xml : local path to the resolved action
configuration
* oozie.action.output.properties : Action properties output as a
Java Properties file

Thx
Alejandro
