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;
...
ColumnFamily: test
Key Validation Class: org.apache.cassandra.db.marshal.BytesType
Default column value validator: org.apache.cassandra.db.marshal.BytesType
Columns sorted by: org.apache.cassandra.db.marshal.BytesType
Row cache size / save period in seconds: 0.0/0
Key cache size / save period in seconds: 200000.0/14400
Memtable thresholds: 0.571875/122/1440 (millions of ops/MB/minutes)
GC grace seconds: 864000
Compaction min/max thresholds: 4/32
Read repair chance: 1.0
Replicate on write: false
Built indexes: []
...
[default@Test] update column family test with comparator = 'LongType';
comparators do not match.
{code}
why?? the CF is empty
{code}
[default@Test] update column family test with comparator = 'BytesType';

[default@Test] update column family test with comparator = 'LongType';
comparators do not match.
{code}
same question than before, my columns contains only long, why I can't?
{code}
[default@Test] update column family test with comparator = 'BytesType';
[default@Test] describe keyspace;

Column Metadata appear from nowhere. I don't think that it's expected.
