Hi Jonathan, we just went through this scenario recently and got this
working. Here are the quick steps…if you have more questions, let me know,
i will hook up with the developer who worked on this.

    1. Hue communicates with JobTracker using Thrift service to get the job

                                Hue --> Thrift --> JobTracker

2.       When the JobTracker starts, it will in-turn try to start the
Thrift service.

3.       The thrift service, to get started, requires
"org.apache.hadoop.thriftfs.ThriftJobTrackerPlugin" class. This class is
taken from the Cloudera distribution. (hue-plugins-2.3.0-cdh4.3.0.jar
located at /usr/lib/hadoop/lib/)


                        We can also build this jar, in Horton by following
the link:

4.       The above said class requires "JobTrackerPlugin" class which is
not available in the Horton distribution. So, need to  add this class to
the library.

This class can be found at<>
