How to set up JMeter for Benchmarking in MetaMatrix?

Issue

I am trying to use JMeter for performance benchmark test and per ServerTuningGuide document,  i need the following JAR files from server installation.  I found first two jar files but not aa.test.metamatrix.jdbc.jmeter.jar.   where can i get the aa.test.metamatrix.jdbc.jmeter.jar ?

a. metamatrix-server.jar
b. MJjdbc.jar
c. aa.test.metamatrix.jdbc.jmeter.jar

Currently without aa.test.metamatrix.jdbc.jmeter.jar,  i am getting below error when i run JMeter run.
