RE: Filtering rows by presence of keys
Bob.Thorman@... 2012-05-22, 17:02
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.
