配置文件
# 五大步骤 主机1 通过选择器 发送到2个channel中 两个channel下沉到不同的另外两台主机中
#本脚本运行在t1主机中
#1. 定义这个agent中各组件的名字
a1.sources = s1
a1.channels = c1 c2
a1.sinks = k1 k2
# 2. 描述和配置source组件：s1
a1.sources.s1.type = exec
a1.sources.s1.command = tail -F /root/app/flumeData/a.log
#关键步骤 复制数据选择器
a1.sources.s1.selector.type = replicating
# 3. 描述和配置channel组件，此处使用是内存缓存的方式
a1.channels.c1.type = memory
a1.channels.c2.type = memory
# 4. 描述和配置sink组件：向哪里发送 指明主机和端口
a1.sinks.k1.type = avro
a1.sinks.k1.hostname = t2
#a1.sinks.k1.type = 8888 导致重大错误
#a1.sinks.k1.port = 8888
a1.sinks.k2.type = avro
a1.sinks.k2.hostname = t3
#a1.sinks.k2.type = 8888 导致重大错误
#a1.sinks.k2.port = 8888
#5.组件关联
a1.sources.s1.channels = c1 c2
a1.sinks.k1.channel = c1
a1.sinks.k2.channel = c2
原因
端口被注释
#a1.sinks.k1.port = 8888
