在独立模式下运行代码时,
laxmikant@laxmikant-Inspiron-1464:~/Work/hadoop-0.21.0$ bin/hadoop jar hadoop-mapred examples-0.21.0.jar grep input output '[a-z.]+'
bash: /home/laxmikant/java/jdk1.7.0_04/bin/java: Permission denied
bash: /home/laxmikant/java/jdk1.7.0_04/bin/java: Permission denied`
怎样才能消除这个错误?我已经正确设置了 java_home 和路径。我试图在网上搜索,但找不到它。您能否发送分配权限和确切步骤所需的命令?
