Driven User Guide
version 1.1.1Visualizing 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.
Once your application is executed in Driven, you can see the DAG representation of the MapReduce job with several flows and their dependencies, as depicted below.

which allows you to drill

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