> The maximum length of the DOS command string is 8191 characters (in Windo=
ws latest versions http://support.microsoft.com/kb/830473). This limit will=
 be exceeded easily when it appends individual =E2=80=93hconf values to the=
 command string. To work around this problem, Write all changed hconf value=
s to a temp file and pass the temp file path to the child jvm to read and i=
nitialize the -hconf parameters from file.
