> 使用taildir实现同时收集文件夹和文件的功能

[tail source官方文档][tail source]

Flume在1.7之前没有提供tail dir source这样的命令，需要自己编译tail dir source的jar包，编译好之后上传到flume的lib目录下，

配置文件参考：

**taildir.properties**

# in this case called 'a1'
    
    a1.sources = s1
    a1.channels = c1
    a1.sinks = k1
    
    # For each one of the sources, the type is defined
    a1.sources.s1.type = org.apache.flume.source.taildir.TaildirSource
    a1.sources.s1.positionFile = /opt/cdhmoduels/apache-flume-1.5.0-cdh5.3.6-bin/taidir/dirsource/taildir_position.json
    a1.sources.s1.filegroups = f1 f2
    a1.sources.s1.filegroups.f1 = /opt/cdhmoduels/apache-flume-1.5.0-cdh5.3.6-bin/taidir/madman.txt
    a1.sources.s1.headers.f1.headerKey1 = value1
    a1.sources.s1.filegroups.f2 = /opt/cdhmoduels/apache-flume-1.5.0-cdh5.3.6-bin/taidir/dirsource/.*
    a1.sources.s1.headers.f2.headerKey1 = value2
    a1.sources.s1.headers.f2.headerKey2 = value2-2
    
    # The channel can be defined as follows.
    a1.sources.s1.channels = c1
    a1.sinks.k1.channel = c1
    
    # Each sink's type must be defined
    a1.sinks.k1.type = hdfs
    a1.sinks.k1.hdfs.path = /flume/event/taildir
    a1.sinks.k1.hdfs.filePrefix = hive-log
    #Specify the channel the sink should use
    
    # Each channel's type is defined.
    a1.channels.c1.type = memory
    
    # Other config values specific to each type of channel(sink or source)
    # can be defined as well
    # In this case, it specifies the capacity of the memory channel
    a1.channels.c1.capacity = 1000
    a1.channels.c1.transactionCapacity = 1000

启动命令

bin/flume-ng agent --conf conf/ --name a1 --conf-file  conf/taildir.properties -Dflume.root.logger=INFO,console
