Ted Yu commented on HADOOP-14178:
---------------------------------
Is this going to hadoop-3 beta / GA ?
If not, how about upgrading to 1.10.19 for hadoop-3 ?
I got the following when starting hadoop-3 mini dfs cluster:
{code}

hbase uses mockito-all 1.10.19
If I downgrade to 1.8.5 (hadoop), hbase code won't compile:
{code}

> 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
> Assignee: Akira Ajisaka
>
> 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.
