Xiao Chen commented on HDFS-9231:
---------------------------------
Per the offline talk, we can make {{FSDirSnapshotOp#getSnapshotFiles}} more
elegant by adding an interface on {{Snapshot}} to get the full snapshot root
path, hence eliminating the need of pass in snapshottableDir. Attached patch 07
to do this. Thanks Yongjun.
> fsck doesn't explicitly list when Bad Replicas/Blocks are in a snapshot

> Currently for snapshot files, {{fsck -list-corruptfileblocks}} shows corrupt
> blocks with the original file dir instead of the snapshot dir, and {{fsck
> -list-corruptfileblocks -includeSnapshots}} behave the same.
> This can be confusing because even when the original file is deleted, fsck
> will still show that deleted file as corrupted, although what's actually
> corrupted is the snapshot.
> As a side note, {{fsck -files -includeSnapshots}} shows the snapshot dirs.
