NameNode不以伪分布模式启动

我无法在hadoop fs -ls/command的HDFS中查看文件，我认为这是因为名称节点没有运行。我尝试过格式化namenode以及将core-site.xml中的端口更改为其他值。即使我的JPS没有列出NameNode。NameNode不以伪分布模式启动

以下是在文件： 1）芯的site.xml

   <configuration> 
         <property> 
         <name>hadoop.tmp.dir</name> 
         <value>/home/hduser/tmp</value> 
         <description>A base for other temporary directories.</description> 
         </property> 
         <property> 
         <name>fs.default.name</name> 
          <value>hdfs://localhost:50000</value> 
          <description>The name of the default file system. A URI whose 
          scheme and authority determine the FileSystem implementation. The 
          uri’s scheme determines the config property (fs.SCHEME.impl) naming 
          the FileSystem implementation class. The uri’s authority is used to 
           determine the host, port, etc. for a filesystem.</description> 
    </property> 
    </configuration>

2）HDFS-site.sml

<configuration> 
          <property> 
          <name>dfs.replication</name> 
           <value>1</value> 
           <description>Default block replication. 
    The actual number of replications can be specified when the file is created. 
    The default is used if replication is not specified in create time. 
    </description> 
    </property> 
    <property> 
     <name>dfs.name.dir</name> 
     <value>/home/hduser/hadoop-1.2.1/data</value> 
    </property> 
    </configuration>

3）mapred-site.xml中

     <configuration> 
        <property> 
     <name>mapred.job.tracker</name> 
          <value>localhost:54311</value> 
      <description>The host and port that the MapReduce job tracker runs 
           at. If “local”, then jobs are run in-process as a single map 
           and reduce task. 
           </description> 
          </property> 
          </configuration>

JPS输出为：

21043的JobTracker

21147的TaskTracker

21789个JPS

20839的DataNode

20957 SecondaryNameNode

谁能帮助？

我卸载，然后重新安装Hadoop的，现在一切工作正常 – Neethu 2014-09-18 23:27:20

如果再次发生同样的问题，则通过rm -rf tmp/删除tmp文件夹中的所有内容，然后格式化namenode，然后应该开始。或者你也可以尝试通过 彬收回的NameNode/HDFS的NameNode -recover

确定。如果需要再次尝试，我会尝试。谢谢您的帮助 – Neethu 2014-09-19 14:35:33
