I just finished an upgrade from cloudbase 1.3.4 to Accumulo 1.4.0. You need to use the upgrade scripts in Accumulo 1.3.5 first, then use the same scripts in Accumulo 1.4.0. They work. The API has changed a bit and the map/reduce configuration is what I'm still working on. Hope it goes well for you...

Adding a filter to the WholeRowIterator has been suggested, and I'm trying that. I'm also pushing for an upgrade from 1.3.4 to 1.4.x, but that may be harder going.
