Examples with WriterHandler org.apache.metron.parsers.bolt.WriterHandler used on opensource projects

Example 1 with WriterHandler

use of org.apache.metron.parsers.bolt.WriterHandler in project metron by apache.

the class ParserTopologyBuilder method createErrorBolt.

/**
 * Create a bolt that handles error messages.
 *
 * @param zookeeperUrl    Kafka zookeeper URL
 * @param brokerUrl    Kafka Broker URL
 * @param sensorType   Type of sensor that is being consumed.
 * @param securityProtocol   Security protocol used (if any)
 * @param configs
 * @param parserConfig
 * @return A Storm bolt that handles error messages.
