flume的导日志数据到hdfs

1.更改配置文件

#agent名， source、channel、sink的名称

a1.sources = r1

a1.channels = c1

a1.sinks = k1

#具体定义source

a1.sources.r1.type = spooldir

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

#具体定义channel

a1.channels.c1.type = memory

a1.channels.c1.capacity = 10000

a1.channels.c1.transactionCapacity = 100

#具体定义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

#不按照条数生成文件

a1.sinks.k1.hdfs.rollCount = 0

#HDFS上的文件达到128M时生成一个文件

a1.sinks.k1.hdfs.rollSize = 134217728

#HDFS上的文件达到60秒生成一个文件

a1.sinks.k1.hdfs.rollInterval = 30

#组装source、channel、sink

a1.sources.r1.channels = c1

a1.sinks.k1.channel = c1

2.把系统组和系统用户改为root

3.更新配置
