Description

Using 5.1.0 rc1, I tried to run an example workflow. Because of user error oozie.wf.application.path in job.properties pointed to a directory in HDFS that did not exist. Upon submitting the workflow, the following was returned

bin/oozie job -oozie http://localhost:11000/oozie   -config examples/apps/demo/job.properties -Dmode=client -Dmaster=yarn -run -DnameNode=hdfs://localhost:9000
log4j:WARN No appenders could be found for logger (org.apache.hadoop.security.authentication.client.KerberosAuthenticator).
log4j:WARN Please initialize the log4j system properly.

Error: E0307 : E0307: Runtime error [Configuration entry oozie.jobs.api.generated.xml not present]

The server.log contained the following:

As a user, I expect to see better error message in order to troubleshoot workflow submission failures.

Note: Earlier (Oozie 5.0) a user got a more descriptive error such as:

Error: E0504 : E0504: App directory [hdfs://test:8020/user/root/examples/apps/demo] does not exist
