Erik Krogen commented on HDFS-13789:
------------------------------------
Hey [~csun], thanks for taking a look. Yes, I agree we should do so, but this
will be a bit more complex work. I created HDFS-13791 to track this, in this
JIRA can we just focus on this log statement which is the most egregious
offender?

> As part of HDFS-13150, a logging statement was added to indicate whenever an
> edit tail is performed via the RPC mechanism. To enable low latency tailing,
> the tail frequency must be set very low, so this log statement gets printed
> much too frequently at an INFO level. We should decrease to DEBUG. Note that
> if there are actually edits available to tail, other log messages will get
> printed; this is just targeting the case when it attempts to tail and there
> are no new edits.
