Description

Adding a name node Element to the FS action will allow users to shorten FS actions and avoid specifying the name node (hdfs://HOST:PORT) multiple times. We can also add job-xml and configuration elements to allow users to set properties when the FS instance is created.

e.g.

<action name="fs-node">
    <fs>
        <name-node>hdfs://host:port</name-node>
        <job-xml>fs-info.xml</job-xml>
        <configuration>
            <property>
                <name>some.property</name>
                <value>some.value</value>
            </property>
        </configuration>
        <mkdir path="/user/${wf:user()}/output-data/1"/>
        <mkdir path="/user/${wf:user()}/output-data/2"/>            
    </fs>
    <ok to="end"/>
    <error to="fail"/>
</action>

This can then also leverage the global section from OOZIE-874 automatically.
