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.
