Passing properties file to Oozie Java Action

Question

I have a Oozie java action workflow set up, which I plan to use an Oozie coordinator to schedule. The java action runs a Camus Job, whose jar and properties config file I have put in the workflow/lib directory. Any ideas on how I would pass the -P argument to this? Currently, I'm doing something like this:

<workflow-app xmlns="uri:oozie:workflow:0.5" name="camus-wf">
    <start to="camusJob"/>
    <action name="camusJob">
        <java>
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <configuration>
            <property>
                    <name>mapred.job.name</name>
                    <value>camusJob</value>
                </property>
                <property>
                    <name>mapred.job.queue.name</name>
                    <value>${queueName}</value>
                </property>
            </configuration>
            <main-class>com.linkedin.camus.etl.kafka.CamusJob</main-class>
    <arg>-P</arg>
    <arg>${camusJobProperties}</arg>
        </java>
        <ok to="end"/>
        <error to="fail"/>
    </action>
    <kill name="fail">
        <message>${wf:errorMessage(wf:lastErrorNode())}</message>
    </kill>
    <end name="end"/>
</workflow-app>

Where camusJobProperties looks like

hdfs://10.0.2.15:8020/coordCamusJob/workflowAppPath/lib/config.properties

But the workflow doesn't seem to run (gets stuck on PREP). Any ideas how to fix this?

Thanks!

EDIT: After correcting my nameNode URL, I can see that I get the following error:

So basically my question is how would I pass the properties file argument when the properties file is located in the HDFS (in particular, in the workflow/lib directory)

Answer 1

For the first part of the question : it might be due to incorrect url of namenode or jobtracker

For the second part : you have to configure the core-site.xml , the property fs.defaultFS to hdfs://host:port/

Also, In your Java program set path of core-site.xml in your config object
