Subject Re: Modifying VisibilityEvaluator - Problem with Classpath for scanner

[Sorry for the re-send, but I think I mistakenly sent to only Ivan before.]

Hi Ivan,

My Accumulo configuration is with everything on a single machine.  Would that matter (would
I have more than one tserver?)?

My situation is like "whack-a-mole" (that's the game where you hit a mole with a hammer and
another one pops up).  What I mean is it seems like I restart Accumulo (bin/ then
bin/ and one time I get one class that is not found, then the next time it seems
like a different class is not found.  Really frustrating. 

So far, as I said, I have put the JARs in lib/ext AND added them to the accumulo-site.xml
:(...  I gave up last night and shut all down and will try again later today.

    Putting the jars in the lib/ext directory is
 a perfectly acceptable mechanism.  Make sure your jars are
 in place on all of your tservers before you start them up. 
 Perhaps this class is being found but is failing to
 initialize itself which can lead to a ClassNoDefError.
