我想使用flume收集python脚本中的日志，所以我按照用户指南用netcat源代码配置flume，然后使用telnet和 nc 对于测试，它工作得很好。
我的配置代码：

a1.sources = r1
a1.sinks = k1
a1.channels = c1
Describe/configure the source
a1.sources.r1.type = netcat
a1.sources.r1.bind = localhost
a1.sources.r1.port = 44444
a1.sinks.k1.type = logger
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

然后我使用python连接flume，并向它发送一些单词，如下所示：

import socket
def netcat(hostname, port):
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((hostname, port))
    s.send("test words 1\n")
    s.send("test words 2\n")
    s.send("test words 3\n")
    s.send("test words 4\n")
    s.shutdown(socket.SHUT_WR)
    s.close()

if _name_ == "_main_":
    netcat("127.0.0.1",44444)

出现问题时，Flume只能接收2行。Flume日志： 2016-12-28 16:44:32,248 (lifecycleSupervisor-1-0) [INFO - org.apache.flume.source.NetcatSource.start(NetcatSource.java:169)] Created serverSocket:sun.nio.ch.ServerSocketChannelImpl[/127.0.0.1:44444] 2016-12-28 16:44:41,814 (SinkRunner-PollingRunner-DefaultSinkProcessor) [INFO - org.apache.flume.sink.LoggerSink.process(LoggerSink.java:95)] Event: { headers:{} body: 74 65 73 74 20 77 6F 72 64 73 20 31 test words 1 } 2016-12-28 16:44:41,815 (SinkRunner-PollingRunner-DefaultSinkProcessor) [INFO - org.apache.flume.sink.LoggerSink.process(LoggerSink.java:95)] Event: { headers:{} body: 74 65 73 74 20 77 6F 72 64 73 20 32 test words 2 } 我在ubuntu&java1.8和centos&java1.7上得到了相同的结果，在python中的telnet模型也得到了相同的结果。
config或python脚本有什么问题吗？或者有人对这个案子有意见吗？
