When I configured oozie, I repeatedly stuck with an error.
$ oozie admin --oozie http://localhost:11000/oozie -status
Error: AUTHENTICATION : Could not authenticate, Authentication failed, status: 404, message: Not found
I thought this was in association with kerberos authentication. Hadoop makes stronger its security by using kereros.
I nearly two weeks for this. You can go to link of the history to solve this problem.
I mainly followed this to configure oozie.
As a reference, I added my modified properties in oozie-html.xml
1) oozie.service.HadoopAccessorService.kerberos.enabled: false
2) oozie.authentication.type: kerberos : simple
Other properties are default values.
If you got an error the same with me, (Error: AUTHENTICATION : Could not authenticate, Authentication failed, status: 404, message: Not found) you should read /var/log/oozie/oozie.log first.
