-------------------------------------

Does anyone know why the dash is there?

> XLogStreamer.constructPattern() contains:
> {code}
> StringBuilder sb = new StringBuilder();
> if (noFilter) {
>     sb.append("(.*)");
> }
> else {
>     sb.append("(.* - ");

>         sb.append(parameters.get(i) + "\\[");
>         sb.append(filterParams.get(parameters.get(i)) + "\\] ");
>     }
>     sb.append(".*)");
> }
> filterPattern = Pattern.compile(sb.toString());
> {code}
> which causes streaming logs to the web UI and CLI to not work if log4j.appender.oozie.layout.ConversionPattern in log4j.properties contains a "-" (dash).  
> We should try to remove this restriction.
