@jsnowacki Thanks for reviewing this PR! There are some situations people
cannot omit the quotes, such as multiple parameters of
"--driver-java-options". For example: [passing multiple -D arguments to
driver-java-options in spark-submit on
windows](https://stackoverflow.com/questions/44578225/passing-multiple-d-arguments-to-driver-java-options-in-spark-submit-on-windows/45972447)
Actually, I find this bug when I try to start a Spark interpreter in Apache
Zeppelin. When SPARK_HOME is set, Zeppelin will add some options to
spark-submit, in these options, there are some quotes, which trigger this bug
in Windows. I trace the launch process of Spark interpreter and finally I found
that it is a bug of Spark. Without this bugfix, Zeppelin cannot start Spark
interpreter when SPARK_HOME is set on Windows.
I will add some comments about these quotes.
