I'm using hector-core 0.8.0-1 and Cassandra 0.8.0 to test a addCounter operation, but I found my code cannot insert any data into the CF, can anyone tell me the reason?
StringSerializer ser = StringSerializer.get();
Mutator<String> mutator = HFactory.createMutator(keyspace, ser);
List<HCounterColumn<String>> counterColumns = Arrays.asList(
HFactory.createCounterColumn("1", 30L, ser),
HFactory.createCounterColumn("2", 20L, ser)
);
for (HCounterColumn c : counterColumns)
{
mutator.addCounter("testKey1", "CounterColumn", c);
mutator.addCounter("testKey2", "CounterColumn", c);
}
mutator.execute();
and I found the following info in my log:
> 2011-06-21 17:17:00,025 [Thread-3]
> INFO me.prettyprint.cassandra.hector.TimingLogger
> - Tag Avg(ms)
> Min Max Std Dev 95th Count 2011-06-21 17:17:00,030
> [Thread-3] INFO me.prettyprint.cassandra.hector.TimingLogger
> - WRITE.fail_ 4.84
> 4.84 4.84 0.00 4.84 1 2011-06-21 17:17:00,031 [Thread-3]
> INFO me.prettyprint.cassandra.hector.TimingLogger
> - META_WRITE.fail_ 17.20

> INFO me.prettyprint.cassandra.hector.TimingLogger
> -
seems something wrong while doing mutator.execute();
Thanks in advance!

This way:
cfDef.setDefaultValidationClass(...)
This is available in the latest version of trunk, 0.7.0 and 0.8.0 branch.
So you need to pull from sources.
or, if you want to do that, and assoming you are using the latest hector available at maven central, you can do this
ThriftCfDef cfDef = new ThriftCfDef(String keyspace, String columnFamilyName, ComparatorType comparatorType)
cf.setDefaultValidationClass(ComparatorType.COUNTERTYPE.getClassName());
cluster.addColumnFamiily(cfDef);

Currently, in Cassandra 0.8.0, you cannot create counter columns in a Column Family that is not specifically created to handle counters:
create column family Counter1 with default_validation_class = CounterColumnType;
