Description

It's really a minor issue.

In ApplicationMaster, there is code like as follows.

      val preserveFiles = sparkConf.get("spark.yarn.preserve.staging.files", "false").toBoolean

I think, the code can be simplified like as follows.

      val preserveFiles = sparkConf.getBoolean("spark.yarn.preserve.staging.files", false)
