我正在使用Cloudera Manager CDH 5.4.2，也安装了Flume，我无法保存从Twitter获得的信息
当我运行水槽代理时，它开始运行正常但在尝试将新事件数据写入hdfs时最终会出错。 我收到以下错误：
INFO org.apache.flume.sink.hdfs.BucketWriter: Creating hdfs://192.168.109.6:8020/user/flume/tweets/2015/06/03/06//FlumeData.1433311217583.tmp
WARN org.apache.flume.sink.hdfs.HDFSEventSink: HDFS IO error
java.net.ConnectException: Call From cluster-05.xxxx.com/192.168.109.6 to cluster-05.xxxx.com:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused
我所做的配置是：
flume-conf.property：
TwitterAgent.sinks.HDFS.channel = MemChannel
TwitterAgent.sinks.HDFS.type = hdfs
TwitterAgent.sinks.HDFS.hdfs.path = hdfs://192.168.109.6:8020/user/flume/tweets/%Y/%m/%d/%H/
TwitterAgent.sinks.HDFS.hdfs.fileType = DataStream
TwitterAgent.sinks.HDFS.hdfs.writeFormat = Text
TwitterAgent.sinks.HDFS.hdfs.batchSize = 1000
TwitterAgent.sinks.HDFS.hdfs.rollSize = 0
TwitterAgent.sinks.HDFS.hdfs.rollCount = 10000
我使用了以下插件：
flume-sources-1.0-SNAPSHOT.jar
twitter4j-core-2.2.6.jar
twitter4j-media-support-2.2.6.jar
twitter4j-stream-2.2.6.jar
（我为twitter4j替换了twitter4j- -3.0.3.jar的版本 - -2.2.6.jar）
也是使用hdfs用户的目录
hadoop fs -ls /user/flume :
drwxrwxrwx - flume flume /user/flume/tweets
core-site.xml（at / hadoop / conf）我添加了：
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:8020</value>
</property>
我还在我离开Flume Agent作为HDFS用户的主机上运行hadoop dfsadmin -safemode
在此问题上，我非常感谢您的帮助。
