Both are attempting to delete columns instead of the intended action of
deleting families. The problem occurs because RowResource.java (line 282) will
always return a split of length 2, since RowSpec.java (line 122) appends a
colon if it's missing.
I've patched it so that a check will occur if the second split's (split[1])
length is 0 and acts accordingly. I'll attach the patch after I've run it
against the test suite.
P.S. It's my first time submitting a patch, so let me know if I screwed
anything up.
