Subject [jira] [Created] (CASSANDRA-2846) Changing replication_factor using "update keyspace" not working
Date Fri, 01 Jul 2011 14:16:28 GMT
Changing replication_factor using "update keyspace" not working
---------------------------------------------------------------

                 Key: CASSANDRA-2846
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2846
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 0.8.1
         Environment: A clean 0.8.1 install using the default configuration
            Reporter: Jonas Borgström


Unless I've misunderstood the new way to do this with 0.8 I think "update keyspace" is broken:

{code}
[default@unknown] create keyspace Test with placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy'
and strategy_options = [{replication_factor:1}];
37f70d40-a3e9-11e0-0000-242d50cf1fbf
Waiting for schema agreement...
... schemas agree across the cluster
[default@unknown] describe keyspace Test;
Keyspace: Test:
  Replication Strategy: org.apache.cassandra.locator.SimpleStrategy
  Durable Writes: true
    Options: [replication_factor:1]
  Column Families:
[default@unknown] update keyspace Test with placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy'
and strategy_options = [{replication_factor:2}];
489fe220-a3e9-11e0-0000-242d50cf1fbf
Waiting for schema agreement...
... schemas agree across the cluster
[default@unknown] describe keyspace Test;                                                
                                                                  Keyspace: Test:
  Replication Strategy: org.apache.cassandra.locator.SimpleStrategy
  Durable Writes: true
    Options: [replication_factor:1]
  Column Families:
{code}

Isn't the second "describe keyspace" supposed to to say "replication_factor:2"?

Relevant bits from system.log:
{code}
Migration.java (line 116) Applying migration 489fe220-a3e9-11e0-0000-242d50cf1fbf Update keyspace
Testrep strategy:SimpleStrategy{}durable_writes: true to Testrep strategy:SimpleStrategy{}durable_writes:
true
UpdateKeyspace.java (line 74) Keyspace updated. Please perform any manual operations
{code}
