Description

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.
