---------------------------------------

             Summary: Updating column family using cassandra-cli results in "Cannot modify
index name"
                 Key: CASSANDRA-4439
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4439
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.1.2
         Environment: cassandra 1.1.2, RHEL6.3, running under java-1.6.0-sun
            Reporter: Alex Schultz


Using cassandra-cli the following update to a column family worked in 1.1.0:
{code}
create keyspace testing;
use testing;

create column family Album
with comparator = UTF8Type
and default_validation_class = UTF8Type
and column_metadata =
[
    {column_name: profileId, validation_class: UTF8Type, index_type: KEYS}
];

update column family Album
and column_metadata =
[
    {column_name: profileId, validation_class: UTF8Type, index_type: KEYS},
    {column_name: postedDate, validation_class: LongType}
];
{code}

After upgrading to 1.1.2, the update statement fails with the following exception in system.log:

After further testing the following works in 1.1.2:
{code}
create keyspace testing;
use testing;
create column family Album
with comparator = UTF8Type
and default_validation_class = UTF8Type
and column_metadata =
[
    {column_name: profileId, validation_class: UTF8Type, index_name: 'Album_profileId_idx',
index_type: KEYS}
];

update column family Album
and column_metadata =
[
    {column_name: profileId, validation_class: UTF8Type, index_name: 'Album_profileId_idx',
index_type: KEYS},
    {column_name: postedDate, validation_class: LongType}
];
{code}

So it appears that if you did not specify an index_name when creating the column originally,
you cannot update the column family anymore.
