             Summary: Documentation issue in wf:lastErrorNode()
                 Key: OOZIE-1975
                 URL: https://issues.apache.org/jira/browse/OOZIE-1975
             Project: Oozie
          Issue Type: Bug
            Reporter: Shwetha G S


According to oozie doc 
http://oozie.apache.org/docs/4.0.1/WorkflowFunctionalSpec.html#a4.2.3_Workflow_EL_Functions,
String wf:lastErrorNode()

It returns the name of the last workflow action node that exit with an ERROR 
exit state, or an empty string if no action has exited with ERROR state in the 
current workflow job.

But according to oozie code, 
{code}
    /**
     * Return the name of the last action that ended in error.
     *
     * @return the name of the last action that ended in error, 
<code>null</code> if no action in the workflow job has
     *         ended in error.
     */
    public static String wf_lastErrorNode() {
        return getWorkflow().getWorkflowInstance().getVar(LAST_ACTION_IN_ERROR);
    }
{code}

So, if there is no error, this EL returns null, but is documented as returning 
empty string
