> We've added support for viewing errors and warnings information in the
> RM/NM/ATS web UI in Dal. To enable the functionality, the appender EWMA has to
> be added to the logger. This can be achieved by appending it to the
> YARN_ROOT_LOGGER environment variable(if the current value is "INFO,RFA", it
> should be set to "INFO,RFA,EWMA".
