核心的site.xml：

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

HDFS-site.xml中：

<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> 

Answer 1

我相信你有你的mapred-site.xml一個錯字。您指定：

<name>mapred.job.tracker></name> 
         ^

但

<name>mapred.job.tracker</name> 

是正確的。注意你的配置文件中</name>之前的錯誤>字符。

如果這沒有幫助，請嘗試https://issues.apache.org/jira/browse/HDFS-2515和Error in starting hadoop Job Tracker。
