Introduction

Karmasphere Studio for Hadoop is a visual development and management environment for the Hadoop map-reduce system. It allows the user to manage, monitor and debug map-reduce jobs, and see the inputs, outputs and intermediate data between the phases of a workflow. It provides real-time accounting and statistics, presents a workflow view of a job which updates in line with the developer's code changes, and generates Java sources and a binary jar file which can be run on a normal Hadoop cluster. Karmasphere Studio also enables analysis and prediction of the behaviour of the map-reduce job.

Karmasphere Studio can be downloaded through the netbeans update center. See the installation guide for details.
