If you are not an Admin make sure you are invoking the oozie client from the correct node. Use localhost only if you are connecting the client from the machine where the oozie server is running. If you are a developer like me who is connecting from an edge node make sure you are exporting the correct URL of oozie the server.

I had a similar problem in my cluster(CDH 5.3.6) running on AWS. I was trying to export the OOZIE_URL just with the host name and port like below

[user@ip-10-241-1-164 ~]$ export OOZIE_URL=http://10.241.1.164:11000/oozie

but it was throwing the same error. It did not like the host name. Finally I have navigated to the Oozie section (find the steps at the end) in Hue and found the oozie.servers value 

oozie.servers
value   ip-10-241-1-111.ec2.internal=http://ip-10-241-1-111.ec2.internal:11000/oozie

copied the value and changed the export command like this

[user@ip-10-241-1-164 ~]$ export OOZIE_URL=http://ip-10-241-1-111.ec2.internal:11000/oozie

and that has fixed my issue.

How to find the oozie.servers value:

  • Open Hue and go to Workflows
  • Navigate to Oozie

Screen shot from Hue

  • Under gauges scroll down until you see oozie.servers name
  • Copy the value and you are done.

It took me 2 days to fix this error. In my case I had 4 Nodes. Oozie was configured in Node 4. But I kept on running the command to name-node which was N1 or hive server which was N3. So make sure you are running command against Oozie server.

Finally I configured the oozie

Steps

  1. Add this line in core-site.xml in hadoop conf

    hadoop.proxyuser.xxx.hosts * hadoop.proxyuser.xxx.groups *

    Here, xxx - User name

  2. Save the conf file and run the code

    oozie job -oozie http://localhost:11000/oozie -config /home/hadoop/Desktop/Cloudera/oozie-2.3.0-cdh3u1/examples/apps/no-op/job.properties -run
