In the Cli, update column family <cf> with comparator; create Column metadata -----------------------------------------------------------------------------
Key: CASSANDRA-2809 URL: https://issues.apache.org/jira/browse/CASSANDRA-2809 Project: Cassandra Issue Type: Bug Components: Tools Affects Versions: 0.8.1 Environment: Ubuntu 10.10, 32bit java version "1.6.0_24" installed from Debian packages of Brisk-beta2 Reporter: Silvère Lestang Using cassandra-cli, I can't update the comparator of a column family with the type I want and when I did it with BytesType, Column metadata appear for each of my existing columns. Step to reproduce: {code} [default@unknown] create keyspace Test with placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy' and strategy_options = [{replication_factor:1}]; [default@unknown] use Test; Authenticated to keyspace: Test [default@Test] create column family test; [default@Test] describe keyspace; ...
