----------------------------------------
Yes, as i can remember i started cqlsh via "cqlsh -3" which is supposed to use
cql 3.0, isn't it. But let me check again.
> Invalid validator used for column values of composite columns -> writing fails
> ------------------------------------------------------------------------------

> Key: CASSANDRA-4421
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4421
> Project: Cassandra
> Issue Type: Bug
> Components: API
> Affects Versions: 1.1.2
> Environment: Debian Squeeze
> Reporter: bert Passek
>
> Hello,
> i faced a bug while writing composite column values and following validation
> on server side.
> This is the setup for reproduction:
> 1. create a keyspace
> create keyspace test with strategy_class = 'SimpleStrategy' and
> strategy_options:replication_factor = 1;
> 2. create a cf via cql (3.0)
> create table test1 (
> a int,
> b int,
> c int,
> primary key (a, b)
> );
> If i have a look at the schema in cli i noticed that there is no column
> metadata for columns not part of primary key.
> create column family test1
> with column_type = 'Standard'
> and comparator =
> 'CompositeType(org.apache.cassandra.db.marshal.Int32Type,org.apache.cassandra.db.marshal.UTF8Type)'
> and default_validation_class = 'UTF8Type'
> and key_validation_class = 'Int32Type'
> and read_repair_chance = 0.1
> and dclocal_read_repair_chance = 0.0
> and gc_grace = 864000
> and min_compaction_threshold = 4
> and max_compaction_threshold = 32
> and replicate_on_write = true
> and compaction_strategy =
> 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy'
> and caching = 'KEYS_ONLY'
> and compression_options = {'sstable_compression' :
> 'org.apache.cassandra.io.compress.SnappyCompressor'};
> Please notice the default validation class: UTF8Type
> Now i would like to insert value > 127 via cassandra client (no cql, part of
> mr-jobs). Have a look at the attachement.
> Batch mutate fails:
> InvalidRequestException(why:(String didn't validate.) [test][test1][1:c]
> failed validation)
> A validator for column value is fetched in
> ThriftValidation::validateColumnData which returns always the default
> validator which is UTF8Type as described above (The ColumnDefinition for
> given column name "c" is always null)
> In UTF8Type there is a check for
> if (b > 127)
> return false;
> Anyway, maybe i'm doing something wrong, but i used cql 3.0 for table
> creation. I assigned data types to all columns, but i can not set values for
> a composite column because the default validation class is used.
> I think the schema should know the correct validator even for composite
> columns. The usage of the default validation class does not make sense.
