Visualizing Custom MapReduce Jobs

Driven supports the operational monitoring of native MapReduce jobs. You can take your existing MapReduce jobs and apply Class MapReduceFlow, which is a HadoopFlow subclass. The Class MapReduceFlow allows custom MapReduce jobs to be observed by Driven.

After Driven receives data from application execution, you can see the directed acyclic graph (DAG) representation of the MapReduce job with flows and their dependencies.

MapReduce_Wrapper Figure 1: Driven displays your MapReduce job DAG representation, which allows you to drill down to a specific flow

Driven does not show any performance data in this example since the job was just launched.
