oozie Pig action lauching Error - hadoop

Question

I am trying to do very basic oozie workflow
I am getting the below error wheni give the command..
user#ubuntu:~/surender$ oozie job -oozie http://localhost:11000/oozie /home/user/surender/oozie_demo/job.properties -run
Error:
Error: E0501 : E0501: Could not perform authorization operation, Failed on local exception: java.io.EOFException; Host Details : local host is: "ubuntu/127.0.0.1"; destination host is: "localhost":8020;
My oozie version is 4.0.0 , I checked that oozie web console is enabled..
This is how created a oozie workflow
I created a directory called oozie_demo and inside that i created two files
1.workflow.xml
2.job.properties
I also created a lib directory and placed the pig script inside that lib directory
workflow.xml
<workflow-app xmlns="uri:oozie:workflow:0.2" name="pig-wf">
<start to="pig-node"/>
<action name="pig-node">
<pig>
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<prepare>
<delete path="${nameNode}/user/${wf:user()}/output/pig/simple_load"/>
</prepare>
<configuration>
<property>
<name>mapred.job.queue.name</name>
<value>${queueName}</value>
</property>
<property>
<name>mapred.compress.map.output</name>
<value>true</value>
</property>
</configuration>
<script>simple_load.pig</script>
<param>INPUT=/user/${wf:user()}/inputfiles/records.txt</param>
<param>OUTPUT=/user/${wf:user()}//output/pig/simple_load</param>
</pig>
<ok to="end"/>
<error to="fail"/>
</action>
<kill name="fail">
<message>Pig failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<end name="end"/>
</workflow-app>
job.properties
nameNode=hdfs://localhost:8020
jobTracker=localhost:8021
queueName=default
oozie_demo=oozie_demo
oozie.use.system.libpath=true
ozie.wf.application.path=${nameNode}/user/user/oozie_demo
my pig script :
records = load '/user/user/inputfiles/records.txt' USING PigStorage(',');
store records into '/user/user/output/pig/simple_load' using PigStorage(',');
Could somebody help me on this? I would like to know what went wrong? and how do i resolve this issue ?

Could you check if the Namenode is up and running at port 8020.
