             Summary: 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


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.
