Jonathan Ellis updated CASSANDRA-1773:
--------------------------------------

    Attachment: 1773-server-side.txt

Patch to validate on the server side attached.

What we still need on the cli side is attempting to convert column_metadata column names into bytes with the comparator instead of assuming utf8; if they fail to convert a client-side error should be raised.

> {code}
> create keyspace clitest with replication_factor = 1 and placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy';
> use clitest;
> create column family bar with column_type = 'Super' and comparator = 'TimeUUIDType' and subcomparator = 'UTF8Type';
> create column family foo with column_type = 'Super' and comparator = 'TimeUUIDType' and subcomparator = 'UTF8Type' and column_metadata=[{column_name:col1, validation_class:UTF8Type}, {column_name:col2, validation_class:UTF8Type}];
> {code}
> then, "describe keyspace clitest" will give "UUIDs must be exactly 16 bytes" because it tries to run "col1" through the comparator getString.
> We should check that column names in metadata match the comparator when updating metadata, and also check that the column names are sane if we update the comparator itself.
