> Current the implementation of LinuxContainerExecutor and container-executor uses some numbers as its commands. The commands begin from zero (INITIALIZE_CONTAINER).
> When LinuxContainerExecutor gives the numeric command as the command line parameter to run container-executor. container-executor calls atoi() to parse the command string to integer.
> However, we know that atoi() will return zero when it can not parse the string to integer. So if you give an non-numeric command, container-executor still accepts it and runs INITIALIZE_CONTAINER command.
> I think it is wrong and we should not use zero as the beginning number of the commands.
