Question

我无法启动namenode。 hadoop版本是hadoop-1.2.1。我已经格式化了名称节点，清除了/ app / hadoop / tmp中的tmp目录。下面提到的是core-site.xml中的配置

<configuration>
     <property>
         <name>fs.default.name</name>
         <value>hdfs://localhost:9000</value>
     </property>
</configuration>>

hdfs-site.xml

<configuration>
     <property>
         <name>dfs.replication</name>
         <value>1</value>
     </property>
</configuration>

mapred-site.xml中

<configuration>
     <property>
         <name>mapred.job.tracker</name>
         <value>localhost:9001</value>
     </property>
</configuration>

这是显示的错误

使用stop-all.sh停止了所有恶魔。清除/tmp目录中的所有文件。使用start-all.sh启动了所有恶魔。

我检查了之前和之后的日志，这是我找到的。

糟糕的日志：

好日志：

也许名称节点没有与脚本格式化，并且我编写了/tmp目录。它开始!!

hadoop单节点：[致命错误] core-site.xml：11：17：尾随部分不允许内容
