本文介绍了Flume配置以上传具有相同名称的文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有10个文件，其中一些数据的长度不同.我想将相应的数据存储在相同的文件中，并使用相同的文件名，但是flume正在拆分数据并将其另存为FlumeData.timestamp.我正在使用以下配置:
I have 10 files with some data varying in length.I would like to store corresponding data in same file and with same filename, but flume is splitting up the data and saving as FlumeData.timestamp. I am using the configuration as below:
a1.sources = r1
a1.sinks = k2
a1.channels = c1
a1.channels.c1.type = file
a1.channels.c1.checkpointDir = /mnt/flume/checkpoint
a1.channels.c1.dataDirs = /mnt/flume/data
a1.channels.c1.trackerDir = /mnt/flume/track
a1.channels.c1.transactionCapacity = 10000000
a1.channels.c1.capacity = 500000000
a1.channels.c1.maxFileSize = 10000000
a1.channels.c1.useDualCheckpoints = true
a1.channels.c1.backupCheckpointDir = /mnt/flume/backup
a1.channels.c1.checkpointInterval = 2000
a1.channels.c1.minimumRequiredSpace = 9000000
a1.sources.r1.channels = c1
a1.sources.r1.type = spooldir
a1.sources.r1.spoolDir = /usr/local/netlog/
a1.sources.r1.fileHeader = true
a1.sources.r1.bufferMaxLineLength = 500
a1.sources.r1.bufferMaxLines = 10000
a1.sources.r1.batchSize = 100000
#a1.sources.r1.deletePolicy = immediate
a1.sinks.k2.type = hdfs
a1.sinks.k2.channel = c1
a1.sinks.k2.hdfs.filePrefix = %{file}
a1.sinks.k2.hdfs.fileType = DataStream
a1.sinks.k2.hdfs.batchSize = 100000
a1.sinks.k2.hdfs.rollSize = 10000000
a1.sinks.k2.hdfs.rollInterval = 0
a1.sinks.k2.hdfs.rollSize = 0
a1.sinks.k2.hdfs.rollCount = 0
a1.sinks.k2.hdfs.idleTimeout = 0
a1.sinks.k2.hdfs.writeFormat = Text
a1.sinks.k2.hdfs.path = /user/flume
# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k2.channel = c1
请建议我如何在其中存储具有相同文件名和数据的相同10个文件.文件大小可以从2 MB到15 MB不等.
Kindly suggest how i can store same 10 files with same filename and data within it. File size can vary from 2 MB to 15 MB.
我在日志中看到的错误是
The error i see in logs is

推荐答案
好的，您还需要HDfs下沉的一些道具:
ok, you need a few more props fro hdfs sink:
a1.sinks.k2.hdfs.filePrefix = [your prefix]
a1.sinks.k2.hdfs.fileSuffix = .[your suffix]
后缀例如是.tsv或.csv，而前缀可以是任何东西-您还可以将变量用于日期和时间-这要求您使用时间戳拦截器.您还可以创建自己的拦截器，并在文件名中生成自己的变量.如果省略此选项，则flume将在前缀和后缀之间添加其自己的序列.
suffix would be .tsv or .csv for instance, while prefix can be anything - you can also use variables for date and time - this requires that you use the timestamp interceptor. You can also create your own interceptor and generate your own variables into your file name. If you omit this, flume will add its own sequence between prefix and suffix.
除了我们之前的评论外，禁用翻转的道具还包括:
As an addition to our previous comments, the props to disable rollovers are the following:
a1.sinks.k2.rollInterval = 0
a1.sinks.k2.rollSize = 0
a1.sinks.k2.rollCount = 0
a1.sinks.k2.idleTimeout = 0
要从源访问原始文件的文件名，请在hdfs接收器配置中添加以下内容:
