问题：EclipseHadoop插件问题（对localhost/127.0.0.1:50070的调用在本地异常上失败：java.io.eofexception）。有人能给我解决这个问题的办法吗？
我正在进行cloudera培训教程。它使用eclipse（helios）3.6和hadoop.0.20.2-cdh3u2版本。
我下载了hadoop-eclipse-plugin-0.20.3-snapshot.jar，并将其复制到/home/training/eclipse/plugins/文件夹中。

Run --> Eclipse --> gone to File (which is in Menu bar) --> New --> other

从其他项目中选择mapreduce项目。我选择了指定hadoop库位置。并指定位置为“/usr/lib/hadoop”。在这个地方我有下面的文件。

bin                                hadoop-examples-0.20.2-cdh3u2.jar
build.xml                          hadoop-examples.jar

将mpareduce项目命名为“myhadoop”，并单击finish按钮。我在dfs的位置按钮得到了mapreduce按钮，但不是hirearchy。
去检查我的dfs和Map端口。
我的core-site.xml是

<configuration>
  <property>
    <name>fs.default.name</name>
    <value>hdfs://localhost:8020</value>
  </property>

我的mapred-site.xml

<configuration>
  <property>
    <name>mapred.job.tracker</name>
    <value>localhost:8021</value>
  </property>

在map reto中定义hadoop在eclipse中的位置，我给出了如下信息。

Map/Reduce Master
Host: localhost
port 50021

DFS Master:
Host :localhost
Port:50020

同时选择使用m/r主机。
我运行了cloudera的示例wordcount程序，但它给了我以下问题。请给我的解决方案，我正在尝试从2天。，。。。。
