This is another topic of heated debate, and it changes from network to network, but I found a simple approach that works in most cases. Since I have four queues and four classes of traffic, I need to categorize my important traffic into four classes. Strictly for explanation purposes I took some liberty in defining four categories of traffic that are very effective in both large and small networks. These classes are: Real Time Protocol (RTP), Network Management (NetMgt), Business Critical, and the Default.

Once you’re doing real development, you’ll want to get into the habit of using smaller, test datasets on your local machine and running your code iteratively in Local Jobrunner Mode (which lets you locally test and debug your Map and Reduce code), then Pseudo-Distributed Mode (which more closely mimics the production environment), then finally Fully-Distributed Mode (your real production cluster). By doing this iterative development, you’ll be able to get bugs worked out on smaller subsets of the data so that when you run on your full dataset with real production resources, you’ll have all the kinks worked out, and your job won’t crash three-quarters of the way in.
