Lars George commented on HBASE-1829:
------------------------------------

Oh, 0.20 branch has old JUnit lib. Hrmm, then we can use it as is as test in trunk is testing
it and since these versions are quite close to each other I trust it works as expected. So
+1 from me for branch.

> Since we can now specify a start and stop row with the Scan that is handed to the TIF
we can reduce the splits to the regions that contain these rows. That allows to test large
MR jobs on a single region for example.
