-----------------------------------------
[~hexiaoqiao] Thanks for the quick update.
We are scared to handle in other shutdown hooks as it close the appender and we
may miss the other log. We have just added here as we expected last log to be
pushed. Whatever the logs in the buffer so far will be flushed and SHUTDOWN
message gets logged.
LM#shutdown() acts on both the the versions.
> Log not flushed fully when NN shutdown
