Mind formatting this to meet the style guide:
```
private[spark] val classLoader =
if (conf.getBoolean("spark.driver.add-dynamic-jars", false)) {
val loader = new SparkURLClassLoader(Array.empty[URL],
this.getClass.getClassLoader)
Thread.currentThread.setContextClassLoader(loader)
Some(loader)
} else {
None
}
```
The only hard requirement is adding brackets and linebreaks around the
`None`. The linebreak at the beginning I don't think we require... that one's
up to you.
