[jira] Created: (HDFS-1341) Provide a mechanism to run functional tests on a real cluster

Provide a mechanism to run functional tests on a real cluster
-------------------------------------------------------------

                 Key: HDFS-1341
                 URL: https://issues.apache.org/jira/browse/HDFS-1341
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: test
    Affects Versions: 0.22.0
            Reporter: Konstantin Boudnik


With Herriot framework (implemented by HADOOP-6332 at all) in place it'd be great to have a way to run on a real cluster all (or as many as possible) functional tests using MiniDFSCluster at the moment.

This might possible be accomplished in two ways:
- by runtime dependency injection to specify underlying cluster abstraction to be chosen (MiniDFSCluster mock or a proxy for real cluster provided by Herriot library)
- by extending MiniDFSCluster to become a transparent adapter between a test and Herriot's real cluster proxy.

Having this in place will tremendously benefit overall quality of HDFS (and potentially all Hadoop) be reusing existing functional testbase for system testing.
