Oozie error when trying to run Pig job workflow - hadoop

Question

I am trying to run a simple Pig job using Oozie 4.0. I am running into the following error. I have created the sharelib folder on the Oozie server at the location /usr/lib/oozie/share/.
I have also pushed the same folder to HDFS at the following locations:
/user/hdfs
/user/oozie
/user/mapred
I have restarted the Hadoop services on the NameNode, Job Tracker and the DataNodes. I did this with the Oozie service stopped and the brought the Oozie service back up using the command:
sudo -u oozie /usr/lib/oozie/bin/oozie-start.sh
I am still getting this error.
cluster_conf.xml:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<property>
<name>nameNode</name>
<value>hdfs://localhost:8020</value>

<value>localhost:8050</value>

<property>
<name>oozie.wf.application.path</name>
<value>/tmp/workflow.xml</value>
</property>
OozieTestScript.pig
A = load '/tmp/passwd' using PigStorage(':');
B = foreach A generate $0 as id;
dump B;
store B into '/tmp/id5.out';
Pig command is simple as shown below. Just note I am keeping the private IPs out of the code copied here.
<pig xmlns="uri:oozie:workflow:0.2">
<job-tracker>172.xx.xx.xx:8050</job-tracker>
<name-node>hdfs://172.xx.xx.xx:8020</name-node>
<script>OozieTestScript.pig</script>
</pig>
