      Description

      The CLI omits CQL3 tables if you do a regular describe command. It also emits a nice warning about it. However, if you do a describe with an explicit CF name, it does something a bit unintuitive:

      [default@ryan] describe r1;
      
      WARNING: CQL3 tables are intentionally omitted from 'describe' output.
      See https://issues.apache.org/jira/browse/CASSANDRA-4377 for details.
      
          ColumnFamily: r1
            Key Validation Class: org.apache.cassandra.db.marshal.Int32Type
            Default column value validator: org.apache.cassandra.db.marshal.BytesType
            Cells sorted by: org.apache.cassandra.db.marshal.CompositeType(org.apache.cassandra.db.marshal.UTF8Type)
            GC grace seconds: 0
            Compaction min/max thresholds: 0/0
            Read repair chance: 0.0
            DC Local Read repair chance: 0.0
            Populate IO Cache on flush: false
            Replicate on write: false
            Caching: keys_only
            Bloom Filter FP chance: default
            Built indexes: []
            Compaction Strategy: null
      

      In this case it emitted the WARNING message, but it still showed the table anyway, and many of the CF settings are incorrect because of this. Better to show nothing than incorrect values.
