Andrés de la Peña created CASSANDRA-7313:
--------------------------------------------

             Summary: SecondaryIndex not deleting column definition
                 Key: CASSANDRA-7313
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7313
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: Andrés de la Peña
            Priority: Minor
         Attachments: dSecondaryIndex-removeColumnDef.diff.txt

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.
