Elise,
Check the tserver_*.{log,out} files. The exception is in the tracer log
is probably a separate issue but won't keep you from running Accumulo.
A good sanity check is to make sure you don't have stray jars in lib and
that ACCUMULO_HOME is correctly set.

I am trying to properly configure Accumulo on a cluster running CDH4.
I can't seem to get any tablet servers up and running.
I've checked out trunk, built it against cdh4, and ran ./accumulo init.
Then I ran the start-all script, which produced the following output:
./start-all.sh
Starting monitor on localhost

When I checked http://localhost:50095/tservers, however, it showed
that there were no tablet servers online. I looked at
http://localhost:50095/log, and saw the following message:
WARN: There are no tablet servers: check that zookeeper and accumulo
are running.
I get the same message when I attempt to start the accumulo shell.
In my tracer_master.debug.log I see the following recurring exception:

Anyone know what could be going on?
Thanks in advance,
