PARQUET-2290: Add CI for Hadoop 2

[Fokko]

Make sure you have checked all steps below.

While upgrading Parquet in Iceberg, I noticed that we broke compatibility. Iceberg is still at Hadoop 2.7.3. The hasCapability method that is used in #951 is not available in Hadoop <2.9.x. There is no serious workaround. I think it is good to add this CI to at least know the lower bound Hadoop 2 version that we're still supporting.

Jira

• My PR addresses the following Parquet Jira issues and references them in the PR title. For example, "PARQUET-1234: My Parquet PR"
  • https://issues.apache.org/jira/browse/PARQUET-2290
  • In case you are adding a dependency, check if the license complies with the ASF 3rd Party License Policy.

Tests

• My PR adds the following unit tests OR does not need testing for this extremely good reason:

Commits

• My commits all reference Jira issues in their subject lines. In addition, my commits follow the guidelines from "How to write a good git commit message":
  1. Subject is separated from body by a blank line
  2. Subject is limited to 50 characters (not including Jira issue reference)
  3. Subject does not end with a period
  4. Subject uses the imperative mood ("add", not "adding")
  5. Body wraps at 72 characters
  6. Body explains "what" and "why", not "how"

Documentation

• In case of new functionality, my PR adds documentation that describes how to use it.
  • All the public functions and the classes in the PR contain Javadoc that explain what it does

This caused issues:

[ERROR] /Users/fokkodriesprong/Desktop/parquet-mr/parquet-thrift/src/main/java/org/apache/parquet/thrift/projection/deprecated/PathGlobPattern.java:[55,49] incompatible types: java.util.regex.Pattern cannot be converted to com.google.re2j.Pattern

Different libraries are used in Hadoop 2 and 3. I think it makes sense to remove this class since it is already marked deprecated for a very long time.

I've removed the static function since it isn't being used in the project.
