Dongjoon Hyun 9c134b57bf [SPARK-32058][BUILD] Use Apache Hadoop 3.2.0 dependency by default 
### What changes were proposed in this pull request?

According to the dev mailing list discussion, this PR aims to switch the default Apache Hadoop dependency from 2.7.4 to 3.2.0 for Apache Spark 3.1.0 on December 2020.

| Item | Default Hadoop Dependency |
|------|-----------------------------|
| Apache Spark Website | 3.2.0 |
| Apache Download Site | 3.2.0 |
| Apache Snapshot | 3.2.0 |
| Maven Central | 3.2.0 |
| PyPI | 2.7.4 (We will switch later) |
| CRAN | 2.7.4 (We will switch later) |
| Homebrew | 3.2.0 (already) |

In Apache Spark 3.0.0 release, we focused on the other features. This PR targets for [Apache Spark 3.1.0 scheduled on December 2020](https://spark.apache.org/versioning-policy.html).

### Why are the changes needed?

Apache Hadoop 3.2 has many fixes and new cloud-friendly features.

- 2017-08-04: https://hadoop.apache.org/release/2.7.4.html
- 2019-01-16: https://hadoop.apache.org/release/3.2.0.html

### Does this PR introduce _any_ user-facing change?

Since the default Hadoop dependency changes, the users will get a better support in a cloud environment.
