Sean Owen updated SPARK-12607:
------------------------------
    Component/s: Windows
        Summary: spark-class.cmd produced null command strings for "exec"  (was: spark-class produced null command strings for "exec")

OK, I don't know Windows well enough to know what the problem or fix is but feel free to propose a change

>                 URL: https://issues.apache.org/jira/browse/SPARK-12607
>             Project: Spark
>          Issue Type: Bug
>          Components: Spark Submit, Windows
>    Affects Versions: 1.4.0, 1.4.1, 1.5.2
>         Environment: MSYS64 on Windows 7 64 bit
>            Reporter: SM Wang
>
> When using the run-example script in 1.4.0 to run the SparkPi example, I found that it did not print any text to the terminal (e.g., stdout, stderr). After further investigation I found the while loop for producing the exec command from the launcher class produced a null command array.
> This discrepancy was observed on 1.5.2 and 1.4.1.  The 1.3.1's behavior seems to be correct.
