目前我正在使用Flume版本：1.5.2。Flume在HDFS輸出文件末尾創建空行
Flume在HDFS中每個輸出文件的末尾創建一個空行，導致行計數，文件大小&校驗和不匹配源文件和目標文件。
我嘗試通過覆蓋參數roolSize，batchSize和appendNewline的默認值，但仍然無法正常工作。
而且水槽從CRLF（來源文件）改變EOL以LF（OUTPUTFILE），這也導致文件大小不同
下面是相關的水槽代理配置參數我使用
agent1.sources = c1
agent1.sinks = c1s1
agent1.channels = ch1
agent1.sources.c1.type = spooldir
agent1.sources.c1.spoolDir = /home/biadmin/flume-test/sourcedata1
agent1.sources.c1.bufferMaxLineLength = 80000
agent1.sources.c1.channels = ch1
agent1.sources.c1.fileHeader = true
agent1.sources.c1.fileHeaderKey = file
#agent1.sources.c1.basenameHeader = true
#agent1.sources.c1.fileHeaderKey = basenameHeaderKey
#agent1.sources.c1.filePrefix = %{basename}
agent1.sources.c1.inputCharset = UTF-8
agent1.sources.c1.decodeErrorPolicy = IGNORE
agent1.sources.c1.deserializer= LINE
agent1.sources.c1.deserializer.maxLineLength = 50000
agent1.sources.c1.deserializer=
org.apache.flume.sink.solr.morphline.BlobDeserializer$Builder
agent1.sources.c1.interceptors = a b
agent1.sources.c1.interceptors.a.type =
org.apache.flume.interceptor.TimestampInterceptor$Builder
agent1.sources.c1.interceptors.b.type =
org.apache.flume.interceptor.HostInterceptor$Builder
agent1.sources.c1.interceptors.b.preserveExisting = false
agent1.sources.c1.interceptors.b.hostHeader = host
agent1.channels.ch1.type = memory
agent1.channels.ch1.capacity = 1000
agent1.channels.ch1.transactionCapacity = 1000
agent1.channels.ch1.batchSize = 1000
agent1.channels.ch1.maxFileSize = 2073741824
agent1.channels.ch1.keep-alive = 5
agent1.sinks.c1s1.type = hdfs
agent1.sinks.c1s1.hdfs.path = hdfs://bivm.ibm.com:9000/user/biadmin/
flume/%y-%m-%d/%H%M
agent1.sinks.c1s1.hdfs.fileType = DataStream
agent1.sinks.c1s1.hdfs.filePrefix = %{file}
agent1.sinks.c1s1.hdfs.fileSuffix =.csv
agent1.sinks.c1s1.hdfs.writeFormat = Text
agent1.sinks.c1s1.hdfs.maxOpenFiles = 10
agent1.sinks.c1s1.hdfs.rollSize = 67000000
agent1.sinks.c1s1.hdfs.rollCount = 0
#agent1.sinks.c1s1.hdfs.rollInterval = 0
agent1.sinks.c1s1.hdfs.batchSize = 1000
agent1.sinks.c1s1.channel = ch1
#agent1.sinks.c1s1.hdfs.codeC = snappyCodec
agent1.sinks.c1s1.hdfs.serializer = text
agent1.sinks.c1s1.hdfs.serializer.appendNewline = false
HDFS。 serializer.appendNewline沒有解決問題。
任何人都可以檢查並建議..
拉傑什感謝爲尋找到這一點。我仍然得到文件大小差異如下所示 – kasi
我仍然得到文件大小的差異。 biadmin @ bivm：〜/ Desktop/work/flume-test/sourcedata1> hadoop fs -copyToLocal hdfs：//bivm.ibm.com：9000/user/biadmin/flume/home/biadmin/Desktop/work/flume-test/sourcedata1/TermDefinition.csv.1452750041843.csv biadmin @ bivm：〜/ Desktop/work/flume-test/sourcedata1> ls -l total 8 -rw-r - r-- 1 biadmin biadmin 754 Jan 14 00： 42 TermDefinition.csv.1452750041843.csv -rwxrw-rw- 1 biadmin biadmin 767 Jan 14 00:06 TermDefinition.csv.COMPLETED biadmin @ bivm：〜/ Desktop/work/flume-test/sourcedata1> – kasi
我的觀察結果是由於此文件大小有所不同，EOL正在從CRLF更改爲LF。我無法分享我的conf文件，因爲此評論部分對要填寫的no.of.characters有限制。你能否建議如何解決這個問題。 – kasi
