Flume+hbase 日志数据采集与存储

了解过flume的人，差不多都看过这张或则类似的图片，本文即实现上图部分内容。（由于条件有限，目前是单机上实现）

flume-agent配置文件

#flume agent conf

source_agent.sources = server
source_agent.sinks = avroSink
source_agent.channels = memoryChannel

source_agent.sources.server.type = exec
source_agent.sources.server.command = tail -F /data/hudonglogs/self/channel.log
source_agent.sources.server.channels = memoryChannel 

source_agent.channels.memoryChannel.type = memory
source_agent.channels.memoryChannel.capacity = 1000
source_agent.channels.memoryChannel.transactionCapacity = 100

source_agent.sinks = avroSink
source_agent.sinks.avroSink.type = avro
source_agent.sinks.avroSink.hostname = 127.0.0.1
source_agent.sinks.avroSink.port = 41414
source_agent.sinks.avroSink.channel = memoryChannel

flume-hbase 配置文件

#hbase flume conf sinks

collector.sources = avroSource
collector.sinks = hbaseSink
collector.channels =memChannel

collector.sources.avroSource.type = avro
collector.sources.avroSource.bind = 127.0.0.1
collector.sources.avroSource.port = 41414
collector.sources.avroSource.channels = memChannel

collector.channels.memChannel.type = memory
collector.channels.memChannel.capacity = 1000

collector.sinks.hbaseSink.type = asynchbase
collector.sinks.hbaseSink.channel = memChannel
collector.sinks.hbaseSink.table = logs
collector.sinks.hbaseSink.columnFamily = content
collector.sinks.hbaseSink.batchSize = 5

hbase中创建表logs 以及列族content

create 'logs','content'

启动flume

nohup $FLUME_HOME/bin/flume-ng agent -c $FLUME_HOME/conf -f $FLUME_HOME/conf/flume-hbase.conf -n collector &
nohup $FLUME_HOME/bin/flume-ng agent -c $FLUME_HOME /conf -f $FLUME_HOME/conf/flume-agent.conf -n source_agent &

注：这两条命令启动是有顺序的，先启动collector，否则会报错

在不断向文件中写入日志后，可以使用scan命令查看hbase

scan 'logs'

另：

　　对于现在的日志格式可能不满意，flume支持自定义Serializer，用于日志的清洗，实现AsyncHbaseEventSerializer接口即可，并将flume重新打包，然后将相应的jar复制到flume home目录下lib文件夹下，旧可以！

接口的实现，参照博文：http://blog.csdn.net/yaoyasong/article/details/39400829
