### What changes were proposed in this pull request?
If you install Spark under the path that has whitespaces, it does not work on Windows, for example as below:
```
>>> SparkSession.builder.getOrCreate()
Presence of build for multiple Scala versions detected (C:\...\assembly\target\scala-2.13 and C:\...\assembly\target\scala-2.12).
Remove one of them or, set SPARK_SCALA_VERSION=2.13 in spark-env.cmd.
Visit https://spark.apache.org/docs/latest/configuration.html#environment-variables for more details about setting environment variables in spark-env.cmd.
Either clean one of them or, set SPARK_SCALA_VERSION in spark-env.cmd.
```
This PR fixes the whitespace handling to support any paths on Windows.
### Why are the changes needed?
To support Spark working with whitespaces in paths on Windows.
### Does this PR introduce _any_ user-facing change?
