flume的導日志資料到hdfs

1.更改配置檔案

#agent名， source、channel、sink的名稱

a1.sources = r1

a1.channels = c1

a1.sinks = k1

#具體定義source

a1.sources.r1.type = spooldir

a1.sources.r1.spoolDir = /root/flume-log

#具體定義channel

a1.channels.c1.type = memory

a1.channels.c1.capacity = 10000

a1.channels.c1.transactionCapacity = 100

#具體定義sink

a1.sinks.k1.type = hdfs

a1.sinks.k1.hdfs.path = hdfs://172.17.14.209:8020/flume/%Y%m%d

a1.sinks.k1.hdfs.filePrefix = events-

a1.sinks.k1.hdfs.fileType = DataStream

a1.sinks.k1.hdfs.useLocalTimeStamp = true

#不按照條數生成檔案

a1.sinks.k1.hdfs.rollCount = 0

#HDFS上的檔案達到128M時生成一個檔案

a1.sinks.k1.hdfs.rollSize = 134217728

#HDFS上的檔案達到60秒生成一個檔案

a1.sinks.k1.hdfs.rollInterval = 30

#組裝source、channel、sink

a1.sources.r1.channels = c1

a1.sinks.k1.channel = c1

2.把系統組和系統使用者改為root

3.更新配置
