Hudson commented on ACCUMULO-956:
---------------------------------

Integrated in Accumulo-Trunk-Hadoop-2.0 #4 (See [https://builds.apache.org/job/Accumulo-Trunk-Hadoop-2.0/4/])
    ACCUMULO-956 generlaized transforming iterator, added some sanity checks to it, added some more unit test, added some static config methods (Revision 1434955)

     Result = FAILURE

> Iterators that transform parts of the key can be tricky if any transformation affects sort ordering.  Implement an iterator that takes care of the tricky details that come with modifying sort order (e.g., handling scan-time iterator reconstruction and the associated seek).
