--------------------------------------
{{spark-submit2.cmd}} is only there for the purpose of isolating environment
problem BTW. Calling {{....2.cmd}} script is fine.
> spark-submit.cmd cannot handle long arguments

> Key: SPARK-22633
> URL: https://issues.apache.org/jira/browse/SPARK-22633
> Project: Spark
> Issue Type: Bug
> Components: Spark Submit
> Affects Versions: 2.1.1
> Environment: Windows 7 x64
> Reporter: Olivier Sannier
> Labels: windows
>
> Hello,
> Under Windows, one would use spark-submit.cmd with the parameters required to
> submit a program to Spark which has the following implementation:
> {{cmd /V /E /C "%~dp0spark-submit2.cmd" %*}}
> This spawns a second shell to ensure changes to the environment are local to
> the script and do not leak to the caller.
> But this has a major drawback as it hits the 2048 characters limit for a
> cmd.exe argument:
> https://support.microsoft.com/en-us/help/830473/command-prompt-cmd--exe-command-line-string-limitation
> One workaround is to call {{spark-submit2.cmd}} directly but it means a
> specific command for Windows usage.
> The other solution is to remove the call to {{cmd}} and replace it with a
> call to {{setlocal}} before calling {{spark-submit2.cmd}} leading to this
> code:
> {{setlocal}}
> {{"%~dp0spark-submit2.cmd" %*}}
> Using this here solved the issue altogether but I'm not sure it can be
> applied to older Windows versions.
