I think Oozie is not running. 

Open the Mozilla Firefox browser in the edureka VM, and enter localhost:11000

If the oozie is not opened, Start the oozie 

Change your directory to oozie 

cd /usr/lib/oozie-4.0.0

Run the oozie :

./bin/oozie-start.sh

You need to add your current user in the HDFS core-site as proxyuser. Add the following configuration in the HADOOP_HOME/conf/core-site.xml:

<property>
  <name>hadoop.proxyuser.current_user.groups</name>
  <value>*</value>
</property>

<property>
  <name>hadoop.proxyuser.current_user.hosts</name>
  <value>host_name_server_running</value>
</property>

In the above replace current_user with the desired user name value and replace host_name_server_running with the name of your server.

Essentially, the user who is running the oozie server process should be added as the proxy user in the core-site.xml. In your case, it happens to be the same user.
