##解决错误：

java.lang.NullPointerException: Expected timestamp in the Flume event headers, but it was null

读取数据通道的方式：

netcat

a1.sources.r1.type = netcat

a1.sources.r1.bind = localhost

a1.sources.r1.port = 12345

根据端口连接传数据

telnet localhost 233333

 

avro

agent1.sources.source1.type = avro

agent1.sources.source1.bind = localhost

agent1.sources.source1.port = 44444

处理序列化数据

 

exec

a1.sources=r1

a1.channels=c1

a1.sources.r1.type=exec

a1.sources.r1.command=tail -F /var/log/secure

a1.sources.r1.channels=c1

处理命令行

 

测试端口

netstat -tnl | grep 23

tcp        0      0 0.0.0.0:36232               0.0.0.0:*                   LISTEN     
tcp        0      0 :::23                       :::*                        LISTEN     

 

访问端口

telnet localhost 23

 

查看端口任务

ps -ef|grep 23

 

 

查看端口占用状态

lsof -i：23
