> Key: HDFS-13092
> URL: https://issues.apache.org/jira/browse/HDFS-13092
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Reporter: Mukul Kumar Singh

>
> ThrottledAsyncChecker.java:schedule prints a log message every time a disk
> check is scheduled. However if the previous check was triggered lesser than
> the frequency at "minMsBetweenChecks" then the task is not scheduled. This
> jira will reduce the log verbosity by printing the message only when the task
> will be scheduled.
