hadoop version命令给出与java相关的错误（没有这样的文件或目录） [英] hadoop version command gives error related to java (No such file or directory)

问题描述

  sagar @ sagar-desktop：〜$ hadoop version 
在运行hadoop命令时出错警告：$ HADOOP_HOME已弃用。 
 Downloads / hadoop-1.2.1 / bin / hadoop：line 350：/usr/lib/java/jdk1.7.0_67/bin/java：没有这样的文件或目录
下载/ hadoop-1.2。 1 / bin / hadoop：第434行：/usr/lib/java/jdk1.7.0_67/bin/java：没有这样的文件或目录
  

java和hadoop路径是

  $ JAVA_HOME = / usr / lib / java / jdk1 .7.0_67 
 $ HADOOP_HOME =下载/ hadoop-1.2.1 
  

请帮助我解决这些错误

解决方案

请阅读此Hadoop维客页面。您需要在 hadoop-env.sh 文件中设置 JAVA_HOME 变量在hadoop / conf目录中，格式化HDFS，然后你可以试试 hadoop version 命令。

I am getting error while running the hadoop command

    sagar@sagar-desktop:~$ hadoop version
    Warning: $HADOOP_HOME is deprecated.
    Downloads/hadoop-1.2.1/bin/hadoop: line 350: /usr/lib/java/jdk1.7.0_67/bin/java: No  such file or directory
    Downloads/hadoop-1.2.1/bin/hadoop: line 434: /usr/lib/java/jdk1.7.0_67/bin/java: No such file or directory

the java and hadoop path are

$JAVA_HOME = /usr/lib/java/jdk1.7.0_67
$HADOOP_HOME = Downloads/hadoop-1.2.1

Please help me in solving these error

解决方案

Please read this Hadoop wiki page. You need to set JAVA_HOME variable in hadoop-env.sh file present in hadoop/conf directory, format HDFS and then you can try hadoop version command.
