使用内存通道增加水槽中的文件大小

以下是我的水槽配置文件。即使在更改rollInterval和rollSize之后,只有10个事件被写入,控制台也会显示rollCount = 10和events = 10。我还尝试将rollCount增加到1000但输出没有变化。任何人都可以建议增加用hdfs写的文件大小。以下conf文件有什么问题?

#naming components 

NetAgent.sources = NetCat_1 NetCat_2
NetAgent.sinks = HDFS
NetAgent.channels = MemChannel


NetAgent.sources.NetCat_1.type = netcat
NetAgent.sources.NetCat_1.bind = localhost
NetAgent.sources.NetCat_1.port = 8671

NetAgent.sources.NetCat_2.type = netcat
NetAgent.sources.NetCat_2.bind = localhost
NetAgent.sources.NetCat_2.port = 8672


NetAgent.sinks.HDFS.type = hdfs
NetAgent.sinks.HDFS.hdfs.path = file path here
NetAgent.sinks.HDFS.hdfs.filePrefix = test
NetAgent.sinks.HDFS.hdfs.rollSize = 67108864
NetAgent.sinks.HDFS.hdfs.rollInterval = 3600
NetAgent.sinks.HDFS.rollCount = 0
NetAgent.sinks.HDFS.hdfs.batchSize = 10000
NetAgent.sinks.HDFS.hdfs.writeFormat = Text
NetAgent.sinks.HDFS.hdfs.fileType = DataStream


NetAgent.channels.MemChannel.type = memory
NetAgent.channels.MemChannel.capacity = 20000
NetAgent.channels.MemChannel.transactionCapacity = 20000


NetAgent.sources.NetCat_1.channels = MemChannel
NetAgent.sources.NetCat_2.channels = MemChannel
NetAgent.sinks.HDFS.channel = MemChannel

控制台记录为

(SinkRunner-PollingRunner-DefaultSinkProcessor) [DEBUg-org.apache.flume.sink.hdfs.BucketWriter.shouldRotate(BucketWriter.java)]
rolling: rollCount: 10, events: 10

您忘了将hdfs添加到rollCount配置中。它使用的默认值为10,因为它看不到您的配置。请注意,您的HDFS配置是:

-g

在rollCount行中,它必须是:

NetAgent.sinks.HDFS.type = hdfs
NetAgent.sinks.HDFS.hdfs.rollSize = 67108864
NetAgent.sinks.HDFS.hdfs.rollInterval = 3600
NetAgent.sinks.HDFS.rollCount = 0
NetAgent.sinks.HDFS.hdfs.batchSize = 10000
NetAgent.sinks.HDFS.hdfs.writeFormat = Text
NetAgent.sinks.HDFS.hdfs.fileType = DataStream

这将覆盖默认的rollCount,您的Flume代理将按您希望的方式运行。
