Figure 4-1. Graph representation of Oozie job flow
The Oozie installation comes with a GUI console for job monitoring, but it requires the use
of Ext JS, a JavaScript framework for building desktop apps that comes with both open
source and commercial versions.
Recently there has been some use of Hue as a more general Hadoop monitoring tool. Hue is
open source, distributed under the Apache License, Version 2.0 and is primarly associated
with the Cloudera Hadoop Distribution.

team and this academic presentation .
