<job-tracker> and <name- node> in oozie pig configuration - where can I find them?

Question

I am trying to start my first oozie workflow, a simple action <pig>.
Can anyone help with these two tags:

    <job-tracker>[JOB-TRACKER]</job-tracker>
    <name-node>[NAME-NODE]</name-node>

As I understand it, the parameters relate to the existing configuration.
I am using a preconfigurered environment, so can you help where to find these values?

If you have access to the Hadoop conf files, open core-site.xml to find the node name from the property below.

 <property>
     <name>fs.default.name</name>
     <value>hdfs://ec2-1-1-1-1.compute-1.amazonaws.com:9000</value>
 </property>

Open the mapred-site.xml file to find the job tracker.

<property>
   <name>mapred.job.tracker</name>
   <value>ec2-1-1-1-1.compute-1.amazonaws.com:54311</value>
</property>

.

nameNode=hdfs://ec2-1-1-1-1.compute-1.amazonaws.com:9000
jobTracker=ec2-1-1-1-1.compute-1.amazonaws.com:54311
