Ozzie pig action stuck in PREP state

I want to run a simple workflow but it gets stuck in PREP state every time i submit the job. Here i am trying to read the values from text file which are comma separated and print them on screen. Fot this i am using following properties file, workflow file and script file.

Environment:
Hadoop: 2.6.0 (1 namenode and 2 datanode)
Oozie : 4.1.0
Pig : 0.14.0

This is my Properties File:
`

<?xml version=”1.0″ encoding=”UTF-8″ standalone=”no”?>
<configuration>
<property>
<name>nameNode</name>
<value>hdfs://<IP/aliasname>:<port></value>
</property>
<property>
<name>jobTracker</name>
<value><IP/aliasname>:<port></value>
</property>
<property>
<name>oozie.libpath</name>
<value><path/to/pig/jars></value>
</property>
<property>
<name>oozie.wf.application.path</name>
<value><path/to/workflow app/in hdfs></value>
</property>
</configuration>

`

This is my Workflow:

<workflow-app name=”samplewrokflow” xmlns=”uri:oozie:workflow:0.2″>
<start to=”TestJob”/>
<action name=”TestJobR”>
<pig>
<job-tracker><IP/alias name>:<port></job-tracker>
<name-node>hdfs://<IP/alias name>:<port></name-node>
<script><Path/to/pig/script></script>
</pig>
<ok to=”success”/>
<error to=”fail”/>
</action>
<kill name=”fail”>
<message>The Identity Map-Reduce job failed!</message>
</kill>
<end name=”success”/>
</workflow-app>

This is my Pig script:

DATA = LOAD ‘path/to/sample.txt’ USING PigStorage(‘,’) as (name1:chararray,name2:chararray,number:int);DUMP DATA;

This is my content in sample.txt:
abc,xyz,1

Command used to run the job:

oozie job –oozie http://<IP address>:<port>/oozie -config <path/to/configuration file> -run

After running this command i get the job Id from screen.

This is my oozie job logs:

2015-06-08 10:58:56,814 INFO ActionStartXCommand:543 – SERVER[pal-hadoop1.cloudapp.net] USER[hadoop1] GROUP[-] TOKEN[] APP[WorkFlow_R] JOB[0000026-150603135220320-oozie-oozi-W] ACTION[0000026-150603135220320-oozie-oozi-W@:start:] Start action [0000026-150603135220320-oozie-oozi-W@:start:] with user-retry state : userRetryCount [0], userRetryMax [0], userRetryInterval [10]

When i get the info using job Id it shows that the job is in PREP state always.

I executed the script independently using pig and it worked fine.

My workflow directory in hdfs structure:

oozie-wf/pigscript.pig
oozie-wf/workflow.xml
oozie-wf/sample.txt
oozie-wf/lib (Contains all pig jar files)

Can you tell me what would be the possible issue here because i could not rectify it from my side? and let me know if you require more details.
