Hi [~chengbing.liu], good callout. I would be supportive of making them static.
Thanks for reporting!

> There are a number of log statements that occur every time new edits are
> tailed by a Standby NameNode. When edits are tailing only on the order of
> every tens of seconds, this is fine. With the work in HDFS-13150, however,
> edits may be tailed every few milliseconds, which can flood the logs with
> tailing-related statements. We should throttle it to limit it to printing at
> most, say, once per 5 seconds.
> We can implement logic similar to that used in HDFS-10713. This may be
> slightly more tricky since the log statements are distributed across a few
> classes.
