Hi,

Oozie prepares a Hadoop configuration file which includes the environments site configuration files (e.g. hdfs-site.xml, mapred-site.xml, etc) plus the properties added to the section of the java action. The Hadoop configuration file is made available as a local file to the Java application in its running directory. It can be added to the java actions Hadoop configuration by referencing the system property: oozie.action.conf.xml . 

For example:

// loading action conf prepared by Oozie
Configuration actionConf = new Configuration(false);
actionConf.addResource(new Path("file:///", System.getProperty("oozie.action.conf.xml")));
