Research direction

Start at ElephantRunner.java:80, where loadAnalyticJobGenerator reports that the Hadoop major version is unsupported, and review the preceding HadoopSecurity login messages. Reproduce the startup on the reported secured cluster and trace Hadoop version detection through the Dr. Elephant log. Done means startup proceeds past this error and job details become available in the web UI.
