Michael Shuler resolved CASSANDRA-10798.
----------------------------------------
    Resolution: Not A Problem

Yeah, I'm calling this not a problem. This is the expected behavior and is documented in NEWS.txt

https://github.com/apache/cassandra/blob/cassandra-2.1.0/NEWS.txt#L31-L36

If you have upgraded nodes from 2.0.x and need new table directories created in the typical 2.1 style, then after you drop {{mytable}}, get your sysadmin to {{rm -r mytable}} before creating it again (or just {{mv}} it, so you have access to snapshots).

> on C* 2.1.12 if you create a new table and a directory with the same name already exist under the keyspace then C* will simply use that directory rather than creating a new one that has uuid in the name.
> Even if you drop and recreate the same table it will still use the previous dir and never switch to a new one with uuid. This can happen on one of the nodes in the cluster while the other nodes will use the uuid format for the same table.
> For example I dropped and recreated the same table three times in this test on a two nodes cluster
> node1
> drwxr-xr-x 3 cassandra cassandra 4096 Dec  1 23:47 mytable

> drwxr-xr-x 2 cassandra cassandra 4096 Dec  1 23:47 mytable-db1b9b41988511e58ce7cfa0aa9730a2
> This seems to break the changes introduced by CASSANDRA-5202
