Subject Re: Hadoop testing project [Was: [VOTE] Abandon mrunit MapReduce contrib]
Date Tue, 15 Feb 2011 22:15:13 GMT
I think this is a good idea. The only thing I think is that it may make
sense to split such an effort into two components: one for the testing of
Hadoop and the projects themselves and one to test end user applications and
libraries. Performance testing tools like YCSB are probably more in the
former camp where mrunit is the latter, as a for instance. I think it's
important to have separate artifacts to minimize uber-jar issues (or
contrib-like situations where release cycles are coupled).
