------------------------------------
Changing it now will break backward compatibility. Lets leave it as is and fix
the doc?
> 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
