> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: HDFS
> Affects Versions: 2.7.0
> Reporter: Lei (Eddy) Xu
> Assignee: Lei (Eddy) Xu
> Attachments: HDFS-8617.000.patch
>
>
> As described in HDFS-8564, {{DiskChecker.checkDirs(finalizedDir)}} is
> causing excessive I/Os because {{finalizedDirs}} might have up to 64K
> sub-directories (HDFS-6482).
> This patch proposes to limit the rate of IO operations in
> {{DiskChecker.checkDirs()}}.
