Is it possible? Sure. But why? What's your use case?

Hi, I wanted to ask if it is possible to intercept every communication that takes place between hadoop's map reduce task i.e between JobTracker and TaskTracker and make it pass through my own communication library. So, if JobTracker and TaskTracker talk through http or rpc, i would like to intercept the call and let it pass through my communication library. If it is possible can anyone tell me that which set of classes i need to look at hadoop's distribution. Similarly, for the hdfs, is it possible to let all the communication that is happening between namenode and datanode to pass through my communication library.
