Using GrovePi with Raspberry Pi and MiNiFi Agents for Data Ingest to Parquet, Kudu, ORC, Kafka, Hive and Impala

Using GrovePi with Raspberry Pi and MiNiFi Agents for Data Ingest Source Code: Acquiring sensor data from Grove sensors is easy using a GrovePi Hat and some compatible sensors. Just before my talk at the Future of Data Meetup @ Bell Works in Holmdel, NJ, I thought I should ingest some data from a grove sensor interface. It's so easy a sleeping cat could do it. So what does this device look like?   I have a temperature and humidity sensor on there. The distance sonic sensor is in there too, that's for the next article. Let's do this with minimal RAM. That's a 64GB hard drive underneath in the white case with the RPI. I need more data and BACON. We design our MiNiFi Agent Flow in CEM/EFM.   Grab JSON data stream and run sensors. Apache NiFi 1.9.2 / CFM 1.0 Received HTTPS S2S Events From MiNiFi Agent A simple flow to query and convert our

Advanced XML Processing with Apache NiFi 1.9.1

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).
