我想水槽與HDFS整合和我的水槽的配置文件是水槽和HDFS集成，HDFS IO錯誤
hdfs-agent.sources= netcat-collect
hdfs-agent.sinks = hdfs-write
hdfs-agent.channels= memoryChannel
hdfs-agent.sources.netcat-collect.type = netcat
hdfs-agent.sources.netcat-collect.bind = localhost
hdfs-agent.sources.netcat-collect.port = 11111
hdfs-agent.sinks.hdfs-write.type = FILE_ROLL
hdfs-agent.sinks.hdfs-write.hdfs.path = hdfs://127.0.0.1:50020/user/oracle/flume
hdfs-agent.sinks.hdfs-write.rollInterval = 30
hdfs-agent.sinks.hdfs-write.hdfs.writeFormat=Text
hdfs-agent.sinks.hdfs-write.hdfs.fileType=DataStream
hdfs-agent.channels.memoryChannel.type = memory
hdfs-agent.channels.memoryChannel.capacity=10000
hdfs-agent.sources.netcat-collect.channels=memoryChannel
hdfs-agent.sinks.hdfs-write.channel=memoryChannel.
而我的核心站點文件
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost</value>
</property>
</configuration>
當我嘗試運行水槽代理，它正在啓動，它能夠從nc命令中讀取，但在寫入hdfs時，我得到以下例外。我試圖用安全模式開始使用hadoop dfsadmin -safemode leave，但我仍然有以下例外。

請讓我知道是否在任何屬性文件中配置了錯誤的東西，以便它可以工作。
也請讓我知道如果我使用的是正確的端口爲這個
我的目標是整合水槽和Hadoop。 我對Hadoop的
