我正在尝试将日志从一个主题转移到另一个主题。我需要用Flume把Kafka和Kafka连接起来。请看下面：

# 

# 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

Flume没有形成。
