Jumbune's Debugger is one of a kind, ultimate tool for hadoop developers. With the increase in analytical engines and parallelism used by them, it is important to analyse and understand the execution flow. This component gives the correlation of data with the execution flow inside the code. The debugger allows you to quickly identify the flaws and bring down debugging time drastically. It provides the number of key and/values that go into each control structure of the MapReduce execution. The user can also add regex or custom validation on top of this for further analysis and development.
