Want to share the log files if you're worried that you're missing
something? I can assure you that Accumulo is not "suppressing real
Exceptions" and giving you "fake" ones.
Also, yes. Accumulo is horizontally scalable. You can run one to many
TabletServers.

Hi,
Thanks.
I was asking on the other reply about trying to get output from my JARs.
The reason I was asking that is that I have a suspicion that the not found errors I am
seeing may be kind of false indication of what is wrong, i.e., there is some other error
or errors, but I am not seeing the output from my JARs, so those errors are hidden, but
the not found errors I am seeing is the "visible" output.

Jim,
All on one machine implies that you
only have one $ACCUMULO_HOME/lib/ext directory. It would
not matter if you are running multiple tservers on that
machine. As Mike suggested, using
$ACCUMULO_HOME/bin/accumulo classpath would help eliminate
whether this is a classpath issue vs a class initialization
issue. Another possible source of issues would be if you
have multiple of the same class on the classpath (different
jars with the same class).
Regards,
Ivan

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/stop-all.sh then
bin/start-all.sh) 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.Thanks,

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.
