> [Byteman|http://byteman.jboss.org/] is an easy to use tool to instrument a java process with agent string.
> For example [this script|https://gist.githubusercontent.com/elek/0589a91b4d55afb228279f6c4f04a525/raw/8bb4e03de7397c8a9d9bb74a5ec80028b42575c4/hadoop.btm] defines a rule to print out all the hadoop rpc traffic to the standard output (which is extremely useful for testing development).
> This patch adds the byteman.jar to the baseimage and defines a simple logic to add agent instrumentation string to the HADOOP_OPTS (optional it also could download the byteman script from an url)
