我正在使用水槽1.5.0.1和hadoop 2.4.1，尝试将字符串放入水槽并保存到HDFS。 Flume配置文件如下:
agentMe.channels = memory-channel
agentMe.sources = my-source AvroSource
agentMe.sinks = log-sink hdfs-sink
agentMe.sources.AvroSource.channels = memory-channel
agentMe.sources.AvroSource.type = avro
agentMe.sources.AvroSource.bind = 0.0.0.0 # i tried client ip as well
agentMe.sources.AvroSource.port = 41414
agentMe.channels.memory-channel.type = memory
agentMe.channels.memory-channel.capacity = 1000
agentMe.channels.memory-channel.transactionCapacity = 100
agentMe.sources.my-source.type = netcat
agentMe.sources.my-source.bind = 127.0.0.1 #If i use any other IP like the client from where the string is going to come from then i get unable to bind exception.
agentMe.sources.my-source.port = 9876
agentMe.sources.my-source.channels = memory-channel
# Define a sink that outputs to hdfs.
agentMe.sinks.hdfs-sink.channel = memory-channel
agentMe.sinks.hdfs-sink.type = hdfs
agentMe.sinks.hdfs-sink.hdfs.path = hdfs://localhost:54310/user/netlog/flume.txt
agentMe.sinks.hdfs-sink.hdfs.fileType = DataStream
agentMe.sinks.hdfs-sink.hdfs.batchSize = 2
agentMe.sinks.hdfs-sink.hdfs.rollCount = 0
agentMe.sinks.hdfs-sink.hdfs.inUsePrefix = tcptest-
agentMe.sinks.hdfs-sink.hdfs.inUseSuffix = .txt
agentMe.sinks.hdfs-sink.hdfs.rollSize = 0
agentMe.sinks.hdfs-sink.hdfs.rollInterval = 3
agentMe.sinks.hdfs-sink.hdfs.writeFormat = Text
agentMe.sinks.hdfs-sink.hdfs.path = /user/name/%y-%m-%d/%H%M/%S
我已经提出了同样的问题here
client.sendDataToFlume("hello world")
我看到NettyAvroRpcClient无法连接到运行水槽的服务器。但是我只是发送一个简单的字符串，我什么都没有。
专家建议
最佳答案
如我所见，如果要与NettyAvroRpcClient连接，则实际上需要设置Avro RPC源。示例配置如下:
# Define an Avro source called AvroSource on SpoolAgent and tell it
# to bind to 0.0.0.0:41414. Connect it to channel MemChannel.
agentMe.sources.AvroSource.channels = MemChannel
agentMe.sources.AvroSource.type = avro
agentMe.sources.AvroSource.bind = 0.0.0.0
agentMe.sources.AvroSource.port = 41414
这将在端口41414上创建一个AvroRPC源。
