Re: Tables showing up as our_table-147a2090ed4211e480153bc81e542ebd/ in data dir

Directory structure is changed in 2.1 to prevent various problems
caused by DROP/re-CREATE the same table
(https://issues.apache.org/jira/browse/CASSANDRA-5202).
>From NEWS.txt:

2.1
===
New features
------------
   ...
   - SSTable data directory name is slightly changed. Each directory will
      have hex string appended after CF name, e.g.
          ks/cf-5be396077b811e3a3ab9dc4b9ac088d/
      This hex string part represents unique ColumnFamily ID.
      Note that existing directories are used as is, so only newly created
      directories after upgrade have new directory name format.
