我正在尝试在amazon linux示例上安装并运行apache storm（1.0.2版）。当我是root用户时启动storm nimbus没有问题。换句话说，如果是，请使用以下命令

sudo su -

python /opt/apache-storm-1.0.2/bin/storm.py nimbus

它工作得很好。但是，如果我是一个ec2用户，并尝试以

sudo python /opt/apache-storm-1.0.2/bin/storm.py nimbus

它给出了以下错误

Traceback (most recent call last):
  File "./storm.py", line 769, in <module>
    main()
  File "./storm.py", line 766, in main
    (COMMANDS.get(COMMAND, unknown_command))(*ARGS)
  File "./storm.py", line 529, in nimbus
    jvmopts = parse_args(confvalue("nimbus.childopts", cppaths)) + [
  File "./storm.py", line 145, in confvalue
    p = sub.Popen(command, stdout=sub.PIPE)

  File "/usr/lib64/python2.7/subprocess.py", line 1343, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

是否仍然可以在不切换为root用户的情况下运行命令
