Exception during connection to ZooKeeperInstance

I am attempting to test out Accumulo for use at work.  I am running into a problem with getting Java code to work.  I am using an Ubuntu VM that came prepared with Acumulo, ZooKeeper, and Hadoop already setup.  I can SSH into the VM, and I can run the Acumulo shell with no problem.  However when running Java code I am running into the Exception below.

Here is my classpath:
accumulo-core-1.4.2
commons-collections-3.2.1
commons-lang-1.0
commons-logging-1.1.1
commons-net-1.4.1
hadoop-core-1.0.1
libthrift-0.9.1
log4j-1.2.16
slf4j-api-1.7.5
slf4j-jdk14-1.7.5
zookeeper-3.4.3

That was it.

I took a look at the class path and just started replacing JARs with the ones already in the project.  The VM uses lib thrift-0.6.1.jar

Thanks Eric

Re: Exception during connection to ZooKeeperInstance

Are you using the same version of hadoop/accumulo as the Accumulo Shell?

You can checkout the accumulo classpath like this:

$ ./bin/accumulo classpath

You are using a slightly newer version of thrift (0.9.1 vs 0.9.0).
