             Summary: Limit logging frequency of edit tail related statements
                 Key: HDFS-13791
                 URL: https://issues.apache.org/jira/browse/HDFS-13791
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: hdfs, qjm
            Reporter: Erik Krogen
            Assignee: Erik Krogen


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.
