> The maximum length of the DOS command string is 8191 characters (in Windows
> latest versions http://support.microsoft.com/kb/830473). This limit will be
> exceeded easily when it appends individual –hconf values to the command
> string. To work around this problem, Write all changed hconf values to a temp
> file and pass the temp file path to the child jvm to read and initialize the
> -hconf parameters from file.
