Flume采集目录及文件到HDFS案例

发布时间:2023-09-06 02:03责任编辑:苏小强关键词:暂无标签

采集目录到HDFS

  使用flume采集目录需要启动hdfs集群

vi spool-hdfs.conf
# Name the components on this agenta1.sources = r1a1.sinks = k1a1.channels = c1# Describe/configure the source##注意:不能往监控目中重复丢同名文件a1.sources.r1.type = spooldira1.sources.r1.spoolDir = /root/logs2a1.sources.r1.fileHeader = true# Describe the sinka1.sinks.k1.type = hdfsa1.sinks.k1.channel = c1a1.sinks.k1.hdfs.path = /flume/events/%y-%m-%d/%H%M/a1.sinks.k1.hdfs.filePrefix = events-
#控制文件夹的滚动频率a1.sinks.k1.hdfs.round = truea1.sinks.k1.hdfs.roundValue = 10a1.sinks.k1.hdfs.roundUnit = minute
#控制文件的滚动频率a1.sinks.k1.hdfs.rollInterval = 3 ?#时间维度a1.sinks.k1.hdfs.rollSize = 20  #文件大小维度a1.sinks.k1.hdfs.rollCount = 5  #event数量维度a1.sinks.k1.hdfs.batchSize = 1a1.sinks.k1.hdfs.useLocalTimeStamp = true#生成的文件类型,默认是Sequencefile,可用DataStream,则为普通文本a1.sinks.k1.hdfs.fileType = DataStream# Use a channel which buffers events in memorya1.channels.c1.type = memorya1.channels.c1.capacity = 1000a1.channels.c1.transactionCapacity = 100# Bind the source and sink to the channela1.sources.r1.channels = c1a1.sinks.k1.channel = c1
mkdir /root/logs2

    spooldir source 监控指定目录 如果目录下有新文件产生 就采集走

    • 注意!!! 此组件监控的目录不能有同名的文件产生 一旦有重名文件:报错 罢工

  启动命令:

bin/flume-ng agent -c ./conf -f ./conf/spool-hdfs.conf -n a1 -Dflume.root.logger=INFO,console

采集文件到HDFS

vi tail-hdfs.conf
# Name the components on this agenta1.sources = r1a1.sinks = k1a1.channels = c1# Describe/configure the sourcea1.sources.r1.type = execa1.sources.r1.command = tail -F /root/logs/test.loga1.sources.r1.channels = c1# Describe the sinka1.sinks.k1.type = hdfsa1.sinks.k1.channel = c1a1.sinks.k1.hdfs.path = /flume/tailout/%y-%m-%d/%H-%M/a1.sinks.k1.hdfs.filePrefix = events-a1.sinks.k1.hdfs.round = truea1.sinks.k1.hdfs.roundValue = 10a1.sinks.k1.hdfs.roundUnit = minutea1.sinks.k1.hdfs.rollInterval = 3a1.sinks.k1.hdfs.rollSize = 20a1.sinks.k1.hdfs.rollCount = 5a1.sinks.k1.hdfs.batchSize = 1a1.sinks.k1.hdfs.useLocalTimeStamp = true#生成的文件类型,默认是Sequencefile,可用DataStream,则为普通文本a1.sinks.k1.hdfs.fileType = DataStream# Use a channel which buffers events in memorya1.channels.c1.type = memorya1.channels.c1.capacity = 1000a1.channels.c1.transactionCapacity = 100# Bind the source and sink to the channela1.sources.r1.channels = c1a1.sinks.k1.channel = c1
mkdir /root/logs

启动命令

bin/flume-ng agent -c conf -f conf/tail-hdfs.conf -n a1

exec source 可以执行一个shell命令 (tail -F sx.log) 实时采集文件数据变化

模拟数据生成的脚步:

while true;do date >> /root/logs/test.log;sleep 0.5;done或 ???#!/bin/bashwhile truedo ?date >> /root/logs/test.log ?sleep 1done
