Pavel Yaskevich commented on CASSANDRA-2809: -------------------------------------------- That column metadata is a feature: when you use a function call in SET statement it is storing information about validation class for individual columns locally (without sync with server) that was added in context of CASSANDRA-1635. +1 of validate patch. > 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 > Environment: Ubuntu 10.10, 32bit > java version "1.6.0_24" > installed from Debian packages of Brisk-beta2 > Reporter: Silvère Lestang > Assignee: Pavel Yaskevich > Priority: Minor > Fix For: 0.8.2 > > Attachments: 2809-validate.txt > > > 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??
