bert Passek created CASSANDRA-4421: -------------------------------------- Summary: 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.
