Review comment:
It would be better to follow here (SparkSubmit.scala#146) to specify
`hadoopConf`.
```scala
val hadoopConf = SparkHadoopUtil.get.newConfiguration(sparkConf)
val ugi = if (args.proxyUser != null) {
UserGroupInformation.createProxyUser(args.proxyUser,
UserGroupInformation.getCurrentUser(hadoopConf))
} else {
UserGroupInformation.getCurrentUser(hadoopConf)
}
```
