> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.0.0, 2.1.0-beta, 0.23.9
> Reporter: Kihwal Lee
> Assignee: Robert Parker
> Fix For: 3.0.0, 0.23.10, 2.1.1-beta

>
> In NamenodeFsck#check(), the getListing() and getBlockLocations() are not
> synchronized, so the file deletions or renames at the right moment can cause
> FileNotFoundException and failure of fsck.
> Instead of failing, fsck should continue. Optionally it can record file
> system modifications it encountered, but since most modifications during fsck
> are not detected, there might be little value in recording these specifically.
