Modifying VisibilityEvaluator - Problem with Classpath for scanner

[o haya <oh...@yahoo.com>]

Hi,

I am trying to make some modifications to the Accumulo VisibilityModifier, but when I add my code, and try to run a scan on a table, I am getting ClassNoDefError for a class that my modified code uses.

So far, what I have been trying to add my JARs to the classpath is to put the JARs in the Accumulo lib/ext directory AND also, editing the accumulo-site.xml and adding the same JARs to that file.  

Is there somewhere else I need to configure or do I need to put the JAR in somewhere other than the lib/ext directory?

Thanks,
Jim

You can use the classpath command to help troubleshoot as well

$ACCUMULO_HOME/bin/accumulo classpath
