Vinay commented on HDFS-5568:
-----------------------------
I found that, if we include snapshot paths in fsck report, cluster health check
will be done properly.
But the small problem is number of files and number of blocks validated will
be more because it may contain duplicates.
So It will be better to make it on demand, and in that case number of blocks
and number of files will not be accurate.

> Support Fsck to check the snapshot paths also for inconsistency.
> Currently Fsck supports snapshot paths if path given explicitly refers to a
> snapshot path.
> We have seen safemode problems in our clusters which were due to blocks
> missing which were only present inside snapshots. But "hdfs fsck /" shows
> HEALTHY.
> So supporting snapshot paths also during fsck (may be by default or on
> demand) would be helpful in these cases instead of specifying each and every
> snapshottable directory.
