Ingesting Drone Data From DJII Ryze Tello Drones Part 1 - Setup and Practice

By Timothy Spann (PaasDev)
Ingesting Drone Data From DJII Ryze Tello Drones Part 1 - Setup and Practice In Part 1, we will setup our drone, our communication environment, capture the data and do initial analysis. We will eventually grab live video stream for object detection, real-time flight control and real-time data ingest of photos, videos and sensor readings. We will have Apache NiFi react to live situations facing the drone and have it issue flight commands via UDP. In this initial section, we will control the drone with Python which can be triggered by NiFi. Apache NiFi will ingest log data that is stored as CSV files on a NiFi node connected to the drone's WiFi. This will eventually move to a dedicated embedded device running MiniFi. This is a small personal drone with less than 13 minutes of flight time per battery. This is not a commercial drone, but gives you an idea of the what you can do with drones. Drone Live Communications for Sensor Readings and Drone Control You must connect t

Advanced XML Processing with Apache NiFi 1.9.1

By Timothy Spann (PaasDev)
Advanced XML Processing with Apache NiFi 1.9.1 With the latest version of Apache NiFi, you can now directly convert XML to JSON or Apache AVRO, CSV or any other format supported by RecordWriters.   This is a great advancement.  To make it even easier, you don't even need to know the schema before hand.   There is a built-in option to Infer Schema. The results of an RSS (XML) feed converted to JSON and displayed in a slack channel. Besides just RSS feeds, we can grab regular XML data including XML data that is wrapped in a Zip file (or even in a Zipfile in an email, SFTP server or Google Docs). Get the Hourly Weather Observation for the United States Decompress That Zip  Unpack That Zip into Files One ZIP becomes many XML files of data. An example XML record from a NOAA weather station. Converted to JSON Automagically Let's Read Those Records With A Query and Convert the results to JSON Records

Connecting Apache NiFi to Apache Atlas For Data Governance At Scale in Streaming

By Timothy Spann (PaasDev)
Connecting Apache NiFi to Apache Atlas For Data Governance At Scale in Streaming Once connected you can see NiFi and Kafka flowing to Atlas. You must add Atlas Report to NiFi cluster. Add a ReportLineageToAtlas under Controller Settings / Reporting Tasks You must add URL for Atlas, Authentication method and if basic, username/password. You need to set Atlas Configuration directory, NiFi URL to use, Lineage Strategy - Complete Path Another example with an AWS hosted NiFi and Atlas: IMPORTANT NOTE:   Keep your Atlas Default Cluster Name  consistent with other applications for Cloudera clusters, usually the name cm is a great option or default . You can now see the lineage state: Configure Atlas to Be Enabled and Have Kafka Have Atlas Service enabled in NiFi configuration Example Configuration You must have access to Atlas Application Properties. /etc/atlas/conf atlas-application.properties   #Generated by Apache
