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

讀取數據通道的方式：
netcat
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 12345
根據端口連接傳數據telnet localhost 233333
avro
agent1.sources.source1.type = avro
agent1.sources.source1.bind = localhost
agent1.sources.source1.port = 44444
處理序列化數據
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
處理命令行
測試端口
netstat -tnl | grep 23
tcp 0 0 0.0.0.0:36232 0.0.0.0:* LISTEN
tcp 0 0 :::23 :::* LISTEN
tcp 0 0 :::23 :::* LISTEN
訪問端口
telnet localhost 23
查看端口任務
ps -ef|grep 23
查看端口占用狀態
lsof -i：23
