Review comment:
Can we introduce a util method `hadoopClassPresent`? We may need this in
other places.
```
private[spark] def hadoopClassPresent: Boolean = {
try {
Utils.classForName("org.apache.hadoop.security.UserGroupInformation")
true
} catch {
case _: ClassNotFoundException | _: NoClassDefFoundError => false
}
}
```
`sys.props.get("user.name").get` => `sys.props("user.name")`
