[jira] [Created] (HADOOP-14178) Move Mockito up to version 2.1.0

Steve Loughran created HADOOP-14178:
---------------------------------------

             Summary: Move Mockito up to version 2.1.0
                 Key: HADOOP-14178
                 URL: https://issues.apache.org/jira/browse/HADOOP-14178
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: test
    Affects Versions: 2.9.0
            Reporter: Steve Loughran
            Priority: Minor


I don't know when Hadoop picked up Mockito, but it has been frozen at 1.8.5 since the switch to maven in 2011. 

Mockito is now at version 2.1, [with lots of Java 8 support|https://github.com/mockito/mockito/wiki/What%27s-new-in-Mockito-2]. That' s not just defining actions as closures, but in supporting Optional types, mocking methods in interfaces, etc. 

It's only used for testing, and, *provided there aren't regressions*, cost of upgrade is low. The good news: test tools usually come with good test coverage. The bad: mockito does go deep into java bytecodes.
