Integrating lucene-geo-gazetteer For Geo Parsing with Apache NiFi   lucene-geo-gazetteer is a very cool Apache Tika, Apache Lucene and Apache OpenNLP tool that builds a fast index of geo data built from a large list of all countries data. It then provides a REST API that we can easily integrate into a flow. So I have connected this to a NiFi flow for enhancing and enriching Twitter data with Geo data. Example NiFi Flow To Convert Twitter Locations Into Geo Information Downloading the Countries Data and Building the Geo Indexes Calling the Local Geo Server Example JSON Data Returned Let's Pull out the fields we want after the split Let's build a new JSON file of just the fields we like including the new geo ones.   Example JSON Processed {"msg":"RT @pauljauregui: Cybersecurity Startups Struggle - https://t.co/wADHLyUEEB #CyberSecurity #AI #IoT #IIoT #IndustrialIoT #DataSecurity #Sec…","unixtime":"1516754942404","friends_count":"4293","sentiment":"NEGATIVE","geolongitude":"-98.5","hashtags":"[\"CyberSecurity\",\"AI\",\"IoT\",\"IIoT\",\"IndustrialIoT\",\"DataSecurity\"]","listed_count":"520","tweet_id":"955965632402485248","user_name":"Lee Weiden","favourites_count":"12454","source":"<a href=\"http://twitter.com\" rel=\"nofollow\">Twitter Web Client</a>","vadersentiment":"Compound -0.3182 Negative 0.161 Neutral 0.839 Positive 0.0 \n","placename":"United States","media_url":"[]","sentiment2":"Negative\n","retweet_count":"0","user_mentions_name":"[]","geo":"","urls":"[]","countryCode":"US","user_url":"","place":"","timestamp":"1516754942404","geolatitude":"39.76","coordinates":"","handle":"LeeWeiden","profile_image_url":"http://xxx.xxxx.com/profile_images/777401884629803009/dUOFoLnt_normal.jpg","time_zone":"Eastern Time (US & Canada)","ext_media":"[]","statuses_count":"186127","followers_count":"1461","location":"United States","time":"Wed Jan 24 00:49:02 +0000 2018","user_mentions":"[]","user_description":"Drivers, Entrepreneur, Family, Faith, Fun, Fitness, Technology, CRM, Social, Mobility & Customer Experience."} Test The API http://localhost:8765/api/search?s=Hightstown&s=New+Jersey Build the Index From All Countries Dataset ./src/main/bin/lucene-geo-gazetteer -i geoIndex -b allCountries.txt Run the REST Server ./src/main/bin/lucene-geo-gazetteer -server Mar 20, 2018 12:33:35 PM org.apache.catalina.core.StandardContext setPath WARNING: A context path must either be an empty string or start with a '/' and do not end with a '/'.

NiFi JSON to DDL Custom Processor Java Class JUnit This is further enhanced version of the idea started here: https://community.hortonworks.com/articles/154957/converting-json-to-sql-ddl.html?es_p=6294995 There was some discussion on linkedin about the previous article being a good processor, so I decided to do that. This is pretty basic, but it handles most types okay. Date and number processing is a bit hacky, but guesses some types. To install, copy the NAR file that you build or download from Github to your NiFi/lib directories and restart those servers. Add the New Processor to Your Flow Configure the Processor with a table type (that is ignored in this version) Configure the Processor with a table name (this is important) JsonToDDLProcessor Generated Docs I configured my table name to be the filename without an extension for JSON Output in NiFi Example Flow Enhancements In Consideration: Apache OpenNLP Apache Tika Attribute Cleaner Enhancement Deep Learning for Determining Types Machine Learning for Type Inference MITIE Apache MXNet TensorFlow Stanford CoreNLP Kite SDK Hive Tools Spark Tools Make Fields Even Sized or Learn What Sizes Are Common Profiling Data Call to the community, if this is interesting, please join. If you don't want to code, please suggest enhancements, open tickets on bugs, spread the word. Thanks.
