Hi experts!
I have a schemaRDD of messages to be pushed in kafka. So I am using
following piece of code to do that
rdd.foreachPartition(itr => {
val props = new Properties()
props.put("metadata.broker.list", brokersList)
props.put("serializer.class",
"kafka.serializer.StringEncoder")
props.put("compression.codec", codec.toString)
props.put("producer.type", "sync")
props.put("batch.num.messages",
BatchSize.toString)
props.put("message.send.max.retries",
maxRetries.toString)
props.put("request.required.acks", "-1")
producer = new Producer[String, String](new
ProducerConfig(props))
itr.foreach(row => {
val msg =
row.toString.drop(1).dropRight(1)
this.synchronized {
producer.send(new
KeyedMessage[String, String](Topic, msg))
}
})
producer.close
})
the problem with this code is that it creates kafka producer separate for
each partition and I want a single producer for all partitions. Is there any
way to achieve this?
