Flume的failover和load balance怎么使用

本篇内容主要讲解"Flume的failover和load balance怎么使用"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"Flume的failover和load balance怎么使用"吧!

一、Load Balancing Sink Processor

===> agent_2

source ==> agent_1 ===> agent_3 ==> Sink

===> agent_4

agent_2,agent_3,agent_4 分担agent_1的数据压力

[root@hftest0001 conf]# pwd/opt/apache-flume-1.6.0-bin/conf[root@hftest0001 conf]# vi s-exec_c-m_s-avro_sp-lb.confagent.sinkgrous.lb-1.sinks = 155-avroSink 154-avroSinkagent.sinkgrous.lb-1.processor.type = load_balance#agent.sinkgrous.lb-1.processor.backoff = trueagent.sinkgrous.lb-1.processor.selector = round_robin#agent.sinkgrous.lb-1.processor.selector.maxTimeOut = 3000agent.sinks.155-avroSink.type = avroagent.sinks.155-avroSink.hostname = ${ip-155}agent.sinks.155-avroSink.port = 55555agent.sinks.155-avroSink.channel = memoryChannelagent.sinks.154-avroSink.type = avroagent.sinks.154-avroSink.hostname = ${ip-154}agent.sinks.154-avroSink.port = 55555agent.sinks.154-avroSink.channel = memoryChannelagent.channels.memoryChannel.type = memoryagent.channels.memoryChannel.capacity = 100

二、Failover Sink Processor

[root@hftest0001 conf]# vi s-exec_c-m_s-avro_sp-fo.conf agent.sinkgrous.lb-1.sinks = 155-avroSink 154-avroSinkagent.sinkgrous.lb-1.processor.type = failoveragent.sinkgrous.lb-1.processor.priority.155-avroSink = 5agent.sinkgrous.lb-1.processor.priority.154-avroSink = 10        => 设置权重agent.sinkgrous.lb-1.processor.maxpenalty = 10000agent.sinks.155-avroSink.type = avroagent.sinks.155-avroSink.hostname = ${ip-155}agent.sinks.155-avroSink.port = 55555agent.sinks.155-avroSink.channel = memoryChannelagent.sinks.154-avroSink.type = avroagent.sinks.154-avroSink.hostname = ${ip-154}agent.sinks.154-avroSink.port = 55555agent.sinks.154-avroSink.channel = memoryChannelagent.channels.memoryChannel.type = memoryagent.channels.memoryChannel.capacity = 100
