Edward Capriolo commented on HIVE-3127:
---------------------------------------
I vote we remove the arguments options entirely. Unix/Linux has the same max
command line argument issue although people hit it less frequently because it
is larger. We do not need two code paths and the performance of writing a file
is nothing compared to overall mr time.
> Don’t pass–hconf values as command line arguments to child JVM to avoid
> command line exceeding char limit on windows

> 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.
