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