> The SnapshotFileCache is checking the lastModificationTime() of the ".hbase-snapshot"
directory.
> But in this way "pending" snapshots created in temp are not considered.
> since only the parent directory timestamp is updated.
> so, if we create .hbase-snapshot/.tmp/SNAPSHOT_NAME the lastModification timestamp of
.hbase-snapshot will not be updated
