>
> The SnapshotFileCache depends on last modified time to determine whether to
> update the Snapshot HFile cache. However, in S3, real 'folders' don't exist.
> S3 filesystems create a dummy file in place of a folder, but the dummy file
> last modified time is not updated when files are changed 'under' it. This
> means that the SnapshotFileCache doesn't pick up new snapshot HFiles and
> these files aren't removed from the HFileCleaner and can be eligible for
> deletion.
>
> My patch removes the lastmodified assumption.
