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
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.
The error i see in logs is

thanks in advance
ok, you need a few more props fro hdfs sink:
a1.sinks.k2.hdfs.filePrefix = [your prefix]
a1.sinks.k2.hdfs.fileSuffix = .[your suffix]
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.
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
to access the file name of the original file from your source, append the following in your hdfs sink config:
a1.sinks.k2.hdfs.filePrefix = %{file}
to simplify your channel config, do the following:
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
Thanks much for your help Erik it helped to go close to the problem i found that flume was creating a file in the data source directory .flumespool which i had to delete along with /mnt/flume/* and also rename the data file to the same name as it was if it was changed to .COMPLETED
