> first if we create one file with some file length and take the snapshot of
> that file,and again append some data through append method to that file,then
> if we do cat command operation on snapshot of that file,in general it should
> dispaly the data what we added with create operation,but it is displaying the
> total data i.e. create +_ appended data.
> but if we do the same operation and if we read the contents of snapshot file
> through input stream it is just displaying the data created in snapshoted
> files.
> in this the behaviour of cat command and reading through inputstream is
> getting different
