Flume监控文件实现断点续传

1、目录配置，实现不了断点续传功能

2、针对采集原始文件实现断点续传（taildir source才有这个断点续传的功能），可以采用多文件进行配置，也可以采用文件通配符进行配置要采集的文件（比如：*.log）

参考：

al.sources = r1
a1.channels = c1
a1.sinks = k1

al.sources.r1.type = TAILDIR
al.sources.r1.positionFile =/home/xxx/position/taildir_position.json
al.sources.r1.filegroups.f1 = f1 f2
al.sources.r1.filegroups.f1=/home/log/log1/*.log
al.sources.r1.filegroups.f1=/home/log/log2/*.log
al.sources.r1.headers.f1.headerKey1 = valuel #headers 的value值
a1.sources.r1.fileHeader=true  #设置文件的绝对路径为 headers的key值


al.channels.cl.type =  file
al.channels.dataDirs = /opt/FLumeclient/datas
al.channels.checkpointDir =/opt/Flumeclient/checkpoint
al.channels.maxFileSize = 2146435071
al.channels.c1.capacity =1000000
al.channels.cl transaction Capacity =500000
al.channels.cl.minimumRequiredSpace =524288000

al.sinks.k1.type = logger
al.sources.r1.channels = c1
al.sinks.k1.channel = c1
