Oozie workflow example failing despite running oozie-setup.sh sharelib with EJ001

[#1]

I'm using Open Source Apache Oozie and I was wondering if perhaps somebody could provide insights into what I'm missing to run the Apache Oozie examples.
I posted all the problem details in

Thank you.

I looked at the source code and looks like this is where the Exception is thrown:

core/src/main/java/org/apache/oozie/action/hadoop/JavaActionExecutor.java

    protected void addSystemShareLibForAction(Configuration conf) throws ActionExecutorException {

        ShareLibService shareLibService = Services.get().get(ShareLibService.class);

        // ShareLibService is null for test cases

        if (shareLibService != null) {

            try {

                List<Path> listOfPaths = shareLibService.getSystemLibJars(JavaActionExecutor.OOZIE_COMMON_LIBDIR);

                if (listOfPaths.isEmpty()) {

                    throw new ActionExecutorException(ActionExecutorException.ErrorType.FAILED, "EJ001",

                            "Could not locate Oozie sharelib");

                }

                addLibPathsToClassPath(conf, listOfPaths);

                addLibPathsToClassPath(conf, shareLibService.getSystemLibJars(getType()));

            }

            catch (IOException ex) {

                throw new ActionExecutorException(ActionExecutorException.ErrorType.FAILED,

                        "Failed to add action specific sharelib", ex.getMessage());

            }

        }

    }
