Flume Failover Sink Processor 故障转移与 Load balancing Sink 负载均衡

接上一篇：https://www.cnblogs.com/jhxxb/p/11579518.html

使用 Flume1 监控一个端口，其 sink 组中的 sink 分别对接 Flume2 和 Flume3，采用 Failover Sink Processor，实现故障转移的功能。

一、创建配置文件

1.flume-netcat-flume.conf

配置 1 个 netcat source 和 1 个 channel、1 个 sink group（2 个 sink），分别输送给 flumeflume-console1 和 flume-flume-console2。

# Name the components on this agent
a1.sources = r1
a1.channels = c1
a1.sinkgroups = g1
a1.sinks = k1 k2

# Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = 127.0.0.1
a1.sources.r1.port = 4444

# Sink Group
a1.sinkgroups.g1.processor.type = failover
a1.sinkgroups.g1.processor.priority.k1 = 5
a1.sinkgroups.g1.processor.priority.k2 = 10
a1.sinkgroups.g1.processor.maxpenalty = 10000

# Describe the sink
a1.sinks.k1.type = avro
a1.sinks.k1.hostname = h136
a1.sinks.k1.port = 4141
a1.sinks.k2.type = avro
a1.sinks.k2.hostname = h136
a1.sinks.k2.port = 4142

# Describe the channel
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.sinkgroups.g1.sinks = k1 k2
a1.sinks.k1.channel = c1
a1.sinks.k2.channel = c1
