数据采集工具之Flume

本文主要实现数据到datahub的采集过程

1、下载

datahub插件下载

https://aliyun-datahub.oss-cn-hangzhou.aliyuncs.com/tools/aliyun-flume-datahub-sink-2.0.9.tar.gz

2、安装

复制代码

$ tar aliyun-flume-datahub-sink-x.x.x.tar.gz
$ cd aliyun-flume-datahub-sink-x.x.x
$ mkdir ${FLUME_HOME}/plugins.d
$ mv aliyun-flume-datahub-sink ${FLUME_HOME}/plugins.d

3、编写配置文件

复制代码

# A single-node Flume configuration for DataHub
# Name the components on this agent
a1.sources = r1
a1.sinks = k1
a1.channels = c1
# Describe/configure the source
a1.sources.r1.type = exec
a1.sources.r1.command = tail -F /soft/data/test.csv
# Describe the sink
a1.sinks.k1.type = com.aliyun.datahub.flume.sink.DatahubSink
a1.sinks.k1.datahub.accessId = 2Z8tAOpDPBm5LEkA
a1.sinks.k1.datahub.accessKey = Tlupsw2G0PdKGCRyPLucHjeESqoCla
a1.sinks.k1.datahub.endPoint = https://datahub.cn-beijing-tbdg-d01.dh.res.bigdata.tbea.com
a1.sinks.k1.datahub.project = bigdata
a1.sinks.k1.datahub.topic = txt_flume
a1.sinks.k1.serializer = DELIMITED
a1.sinks.k1.serializer.delimiter = ,
a1.sinks.k1.serializer.fieldnames = id,name,gender,salary,my_time,decimal
a1.sinks.k1.serializer.charset = UTF-8
a1.sinks.k1.datahub.retryTimes = 5
a1.sinks.k1.datahub.retryInterval = 5
a1.sinks.k1.datahub.batchSize = 100
a1.sinks.k1.datahub.batchTimeout = 5
a1.sinks.k1.datahub.enablePb = true
a1.sinks.k1.datahub.compressType = DEFLATE
# Use a channel which buffers events in memory
a1.channels.c1.type = memory
a1.channels.c1.capacity = 10000
a1.channels.c1.transactionCapacity = 10000
# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

4、启动

复制代码

flume-ng agent -n a1 -c conf -f ./conf/flume-txt2datahub.conf -Dflume.root.logger=INFO,console

Q:启动报错

复制代码

A:删除Flume lib文件夹中的guava jar包文件，重新启动
