Description

When latest master Oozie is built locally with Hadoop version 2.6.0, and bin/oozied.sh start is issued, reaching the UI or accessing CLI results in following error message:

{"errorMessage":"org.apache.jasper.JasperException: Unable to compile class for JSP","httpStatusCode":500}

Server side error message in logs/jetty.log is:

From CLI, following is the error message:

Error: IO_ERROR : java.io.IOException: Error while connecting Oozie server. No of retries = 1. Exception = Could not authenticate, Authentication failed, status: 404, message: Not Found

Oozie 5.0.0 UI and CLI both work in the same environment.
