Review comment:
First, I want to use WARN or even ERROR level, but the frequency of
checkpoint may be too small, we may have logging flood if use INFO or above log
level, so I used debug here. If we do not have so frequent checkpoints, we can
configure the log level of log-4j properties to show this log. what do you
think about this?
