Cassandra 3.10 Create Trigger, class doesn't exist - cassandra

Question

I have DSE 5.1 with Cassandra 3.10 and cql 5.0.1 installed on CentOS 7.3.1611 (Core).
I'm following the tutorial from DSE Triggers:
http://docs.datastax.com/en/dse/5.1/cql/cql/cql_reference/cql_commands/cqlCreateTrigger.html?hl=trigger
Which send me to github:
https://github.com/apache/cassandra/tree/trunk/examples/triggers
According to the tutorial, I am compiling the jar with ANT 1.10.1. The compiled jar contain the code:
package org.apache.cassandra.triggers;
import java.io.InputStream;
import java.util.Collection;
import java.util.Collections;
import java.util.Properties;
import org.apache.cassandra.schema.TableMetadata;
import org.apache.cassandra.schema.Schema;
import org.apache.cassandra.db.Mutation;
import org.apache.cassandra.db.partitions.Partition;
import org.apache.cassandra.db.partitions.PartitionUpdate;
import org.apache.cassandra.io.util.FileUtils;
import org.apache.cassandra.utils.FBUtilities;
import org.apache.cassandra.utils.UUIDGen;
public class AuditTrigger implements ITrigger
{
private Properties properties = loadProperties();
public Collection<Mutation> augment(Partition update)
{
String auditKeyspace = properties.getProperty("keyspace");
String auditTable = properties.getProperty("table");
TableMetadata metadata = Schema.instance.getTableMetadata(auditKeyspace, auditTable);
PartitionUpdate.SimpleBuilder audit = PartitionUpdate.simpleBuilder(metadata, UUIDGen.getTimeUUID());
audit.row()
.add("keyspace_name", update.metadata().keyspace)
.add("table_name", update.metadata().table)
.add("primary_key", update.metadata().partitionKeyType.getString(update.partitionKey().getKey()));
return Collections.singletonList(audit.buildAsMutation());
}
private static Properties loadProperties()
{
Properties properties = new Properties();
InputStream stream = AuditTrigger.class.getClassLoader().getResourceAsStream("AuditTrigger.properties");
try
{
properties.load(stream);
}
catch (Exception e)
{
throw new RuntimeException(e);
}
finally
{
FileUtils.closeQuietly(stream);
}
return properties;
}
}
The compiled jar, I am copying to the cassandra triggers location (/etc/cassandra/triggers). Then I run from cql the command:
CREATE TRIGGER test1 ON test.test USING 'org.apache.cassandra.triggers.AuditTrigger';
And send me the error:
ConfigurationException: Trigger class 'org.apache.cassandra.triggers.AuditTrigger' doesn't exist
I copied the jar in all the nodes of my cluster, restarted the cluster and ran the command:
nodetool reloadtriggers
With no success, I also put in the jvm.options the command:
-Dcassandra.triggers_dir=/etc/dse/cassandra/triggers
And in the cassandra-env.sh, I added the command:
JVM_OPTS="$JVM_OPTS -Dcassandra.triggers_dir=/etc/dse/cassandra/triggers"
And I am getting the same error. I tryied adding the jar in the cassandra lib folder (/usr/share/dse/cassandra/lib/) and it seems to not been loading the compiled jar.
When I run the command in cql:
CREATE TRIGGER test1 ON test.test USING 'org.apache.cassandra.triggers.AuditTrigger';
I am still getting the same error
ConfigurationException: Trigger class 'org.apache.cassandra.triggers.AuditTrigger' doesn't exist
So, my question is, How can I make cassandra load my jar correctly and use it to create a trigger in cql?
