I am running the workflow in the cloudera quickstart vm 5.7.2 I am able to run the job from the command line but then in hue it just freezes gives the error  JA009: Cannot initialize Cluster. Please check your configuration for mapreduce.

Here is my workflow.xml 

<workflow-app name="sample-workflow" xmlns="uri:oozie:workflow:0.5">
<global>
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
</global>

<start to="sshScript"/>

<action name="sshScript">
<shell xmlns="uri:oozie:shell-action:0.3">
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<exec>hello.sh</exec>
<argument>44 </argument>
<file>/user/cloudera/hive-config.xml#hive-config.xml</file>
</shell>
<ok to="end"/>
<error to="fail"/>

</action>

<kill name="fail">
<message>Failed script</message>
</kill>
<end name='end'/>

</workflow-app>

and my job.properties

oozie.use.system.libpath=True
security_enabled=False
dryrun=False
queueName=default
nameNode=quickstart.cloudera:8020
jobTracker=quickstart.cloudera:8032
oozie.libpath=/user/hue/oozie/workspaces/sampleScript/
oozie.wf.application.path=/user/hue/oozie/workspaces/sampleScript/workflow.xml

Thanks
