Matias,

I can see this class exists in the 0.21 branch. Please note that from
0.21, the project is split into 3: common, hdfs and mapreduce. The
MiniMRCluster is in the mapreduce project:
hadoop.apache.org/mapreduce. That said, the class is still using some
of the older classes like you mention. Please note that many of the
framework tests still rely on the MiniMRCluster.

Thanks
Hemanth
