如何使用Flume将主题从kafka转换为kafka？

Question

I am trying transfer log from topic to another topic. I need connect Kafka to Kafka using Flume. Take a look below:

#
# Flume Conf
#

a1.sources = s1
a1.sinks = k1
a1.channels = c1


# Kafka Source

a1.sources.s1.type = org.apache.flume.source.kafka.KafkaSource
a1.sources.s1.kafka.bootstrap.servers = kafka:9092
a1.sources.s1.kafka.topics = apache


# Kafka Sink

a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
a1.sinks.k1.kafka.bootstrap.servers = kafka:9092


# Use a channel which buffers events in memory

a1.channels.c1.type = memory
a1.channels.c1.capacity = 10000000
a1.channels.c1.transactionCapacity = 1000000


# Bind the source and sink to the channel

a1.sources.s1.channels = c1
a1.sinks.k1.channel = c1

The sink are not creating.

If you want to replicate data from one Kafka cluster to another, there are better ways than Flume, including:

• MirrorMaker , as @cricket_007 mentioned (open source, part of Apache Kafka)
• Confluent's Replicator (commercial tool, 30 day free trial)
• uReplicator ( open sourced from Uber)
• Mirus ( open sourced from Salesforce)
• Brucke (open source)

If you want a really dirty hack, you can also do something with kafkacat and nc .
