> Currently, taking a snapshot will not create the family directory under a region if the
family does not have any files in it. 
> Subsequent verification fails because of this. There is some logic in the SnapshotTestingUtils.confirmSnapshotValid()
to deal with empty family directories, but I think we should create the family directories
regardless of whether there are any hfiles referencing them.
