Requirements

1. Install Pylint from Install. If you have anaconda already installed use pip install -U pylint to update the Pylint so that pyreverse is added to the scripts folder.
2. You need to install Graphviz as the pyreverse generates the UML diagrams in dot format and needs the dot.exe provided by Graphviz. Once Graphviz is installed make sure the bin folder is added to the PATH variable so that pyreverse can find it at run time. "the command pyreverse generates the diagrams in all formats that graphviz/dot knows." (Reference
3. Now add the path of python modules for which you want to generate the documentation to PYTHONPATH.

4. Use pyreverse -S <modulename> to generate dot files in the current folder

NiFi Example: SQS Consumer Distribution

This Gist contains a NiFi flow template that utilizes NiFi backpressure mechanizm to distribute load among multiple consumers.

This pattern is useful to consume large data from AWS, downloading large files from S3 for instance.

The key point is configure GetSQS processor Batch Size to 1. It defaults to 10, so you may not be able to see expected distribution with small number of messages.

Set Back Pressure Object Threshold to 1 at the success relationship from GetSQS, so that only one flow file can be processed at a time.

FFmpeg has been removed from Ubuntu 14.04 and was replaced by Libav. This decision has been reversed so that FFmpeg is available now in Ubuntu 15.04 again, but there is still no official package for 14.04. In this tutorial, I will show you how to install FFmpeg from mc3man ppa. Add the mc3man ppa:

sudo add-apt-repository ppa:mc3man/trusty-media
And confirm the following message by pressing <enter>:

Also note that with apt-get a sudo apt-get dist-upgrade is needed for initial setup & with some package upgrades
