Error E0902 in Launching any Oozie workflow through Hue (Exception occured: [failure to login])?

[ Edited ]



I have a single Hadoop cluster with 1 NameNode, 1 SecondaryNameNode and 3 DataNodes. I installed Cloudera Standard and I have a strange error when I launch any type of Oozie workflow through Hue, also an empty workflow.

The error in Hue WEB UI is:

Error submitting workflow Prova_workflow_vuoto - hue

E0902: Exception occured: [failure to login]

instead in Oozie service log the error is:

org.apache.oozie.service.AuthorizationException: E0902: Exception occured: [failure to login]
at org.apache.oozie.service.AuthorizationService.authorizeForApp(
at org.apache.oozie.servlet.BaseJobServlet.checkAuthorizationForApp(

and in the same file there was written:

Caused by: org.apache.oozie.service.HadoopAccessorException: E0902: Exception occured: [failure to login]
at org.apache.oozie.service.HadoopAccessorService.createFileSystem(
at org.apache.oozie.service.AuthorizationService.authorizeForApp(
... 25 more
Caused by: failure to login
at org.apache.oozie.service.HadoopAccessorService.getUGI(
at org.apache.oozie.service.HadoopAccessorService.createFileSystem(
... 26 more
Caused by: java.lang.NullPointerException
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

Any suggestion?

As you can note from the JVM classname above, you are apparently (intentionally or accidentally) using an IBM JVM instead of the recommended Sun/Oracle JVM.

The IBM JVM has not been tested to work with CDH4 releases and we would recommend using the Oracle JVM to resolve your problem.
