安装hadoop遇到的问题

1.  

root@iZ9481a72tjZ:~# jps
The program 'jps' can be found in the following packages:
* openjdk-6-jdk
* openjdk-7-jdk
Try: apt-get install <selected package>

 

用  java -version

root@iZ9481a72tjZ:~# java -version
java version "1.7.0_72"
Java(TM) SE Runtime Environment (build 1.7.0_72-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.72-b04, mixed mode)

是能够看到 java 版本的，只是查看进程不行

 

solution：

 sudo update-alternatives --install /usr/bin/jps jps /home/hadoop/jdk1.7.0_72/bin/jps 1

找了一天，才搞定
