官网中虽然说没有key 会随机分配到partition,但是不知道为什么在我这没有出现这种效果,所以我加了一个key,需要加个source拦截器
运行flume-ng agent --conf conf --conf-file test.sh --name a1 -Dflume.root.logger=INFO,console
# example.conf: A single-node Flume configuration
# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# Describe/configure the source
a1.sources.r1.type =exec
a1.sources.r1.command =tail -F /opt/access.log
# Describe the sink
a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink
a1.sinks.k1.topic = test
a1.sinks.k1.brokerList = node1:9092,node2:9092,node3:9092
a1.sinks.k1.metadata.broker.list = node1:9092,node2:9092,node3:9092
a1.sinks.k1.requiredAcks = 1
a1.sinks.k1.batchSize = 20
a1.sinks.k1.channel = c1
#source 拦截器
a1.sources.r1.interceptors = i2
a1.sources.r1.interceptors.i2.type = org.apache.flume.sink.solr.morphline.UUIDInterceptor$Builder
a1.sources.r1.interceptors.i2.headerName = key
a1.sources.r1.interceptors.i2.preserveExisting = false
# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1
