如何在ftp源水槽代理中保留文件的原始基名

提问于

我配置了一个水槽代理，它从FTP服务器读取并将文件发送到hdfs接收器 . 我的大问题是，我想用原始文件名存储hdfs中的文件 . 我尝试使用Spooldir源代码，它工作正常并且能够使用它们的基本名称在hdfs中存储文件，但是flume agent crush：

1）如果在放入假脱机目录后写入文件，Flume会在其日志文件中输出错误并停止处理 .

2）如果文件名稍后重复使用，Flume会在其日志文件中输出错误并停止处理 .

事实上，spooldir-source不适合我的用例 . 那么，有没有想法如何使ftp源保持文件名，随后，hdfs根据其名称分别存储文件 .

这是我的经纪人：

agent.sources = r1
agent.channels = c1
agent.sinks = k

#configure ftp source
agent.sources.r1.type = org.keedio.flume.source.mra.source.Source
agent.sources.r1.client.source = sftp
agent.sources.r1.name.server = ip
agent.sources.r1.user = user
agent.sources.r1.password = pwd
agent.sources.r1.port = 22
agent.sources.r1.knownHosts = ~/.ssh/known_hosts
agent.sources.r1.work.dir = /DATA/flume_ftp_source
agent.sources.r1.fileHeader = true
agent.sources.r1.basenameHeader = true
agent.sources.r1.inputCharset = ISO-8859-1
agent.sources.r1.flushlines = true

#configure sink s1
agent.sinks.k.type = hdfs
agent.sinks.k.hdfs.path =  hdfs://hostname:8020/user/admin/DATA/import_flume/agents/agent1/%Y/%m/%d/%H
agent.sinks.k.hdfs.filePrefix = %{basename}
agent.sinks.k.hdfs.rollCount = 0
agent.sinks.k.hdfs.rollInterval = 0
agent.sinks.k.hdfs.rollSize = 0
agent.sinks.k.hdfs.useLocalTimeStamp = true
agent.sinks.k.hdfs.batchsize =    1000000
agent.sinks.k.hdfs.fileType = DataStream

agent.channels.c1.type = memory
agent.channels.c1.capacity =  1000000
agent.channels.c1.transactionCapacity =   1000000

agent.sources.r1.channels = c1
agent.sinks.k.channel = c1

    我刚推出了一个解决方案来解决flume ftp github项目：

    Is there a trick on how to fix the fact that the property % is missing ?

    正如我所说，根据以下代码更新：Fix for Flume FTP source，这是我使用％变量的方式：
