Guillaume Vauvert commented on MRUNIT-196:
------------------------------------------

I believed that I had the same issue, but I was using hadoop-core.1.2.1 with mrunit-hadoop2-1.1.0
.

> I've done a little more digging and it looks like {{AbstractMockContextWrapper}} just
hasn't educated itself that {{TaskInputOutputContext}} changed from a class in v1 to an interface
in v2:
