> The method _SecondaryIndex#removeColumnDef_ does not delete the requested column definition. I think this may be due to the iterator's remove method:
> {code:java}
> void removeColumnDef(ByteBuffer name)
>     {
>         Iterator<ColumnDefinition> it = columnDefs.iterator();
>         while (it.hasNext())
>         {
>             if (it.next().name.bytes.equals(name))
>                 it.remove();
>         }
>     }
> {code}
> For me it has been problematic when deleting a per row index in a column family and then creating a new one.
> I attach a patch that may solve the problem.
