The program 'jps' can be found in the following packages:
 * openjdk-8-jdk-headless
 * openjdk-9-jdk-headless
Try: sudo apt install <selected package>
rana@ubuntu:/usr/local/hadoop/hadoop-2.7.3/bin$ sudo jps
sudo: jps: command not found

您应该在环境文件中将JAVA_HOME/bin地址添加到PATH,我的意思是bashrc。因此,使用命令nano ~/.bashrc打开环境文件,然后在文件末尾添加行export PATH=$JAVA_HOME/bin:$PATH,并按control + x保存。关闭文件后,使用命令source ~/.bashrc编译文件并更新到新设置。现在JPS命令将起作用!

我有同样的问题,我通过输入以下内容解决了我的问题: -

sudo apt install openjdk-8-jdk-headless

希望这个有用:)
