Subject: [HOT-FIX] Recover some deprecations for 2.10 compatibility.

## What changes were proposed in this pull request?

#11479 [SPARK-13627] broke 2.10 compatibility: [2.10-Build](https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Compile/job/spark-master-compile-maven-scala-2.10/292/console)
At this moment, we need to support both 2.10 and 2.11.
This PR recovers some deprecated methods which were replace by [SPARK-13627].

## How was this patch tested?

Jenkins build: Both 2.10, 2.11.

Author: Dongjoon Hyun <dongjoon@apache.org>

Closes #11488 from dongjoon-hyun/hotfix_compatibility_with_2.10.
