I need to be able to JSONize and return json:chararray's of any pig datatypes, to be able to index complex types in ElasticSearch via Wonderdog. See: https://issues.apache.org/jira/browse/PIG-2641
Does anyone have existing code they can contribute to a toJSON UDF that handles all these types? For instance, Mozilla has this Map to JSON UDF: https://github.com/mozilla-metrics/akela/blob/master/src/main/java/com/mozilla/pig/eval/json/MapToJson.java It is apache licensed, so I think I can paste it into a general toJSON UDF? Elephant-bird has this code, which turns JSON to Maps: https://github.com/kevinweil/elephant-bird/blob/master/src/java/com/twitter/elephantbird/pig/piggybank/JsonStringToMap.java ehh... thinking out loud... I'm just gonna do this in JRuby. If that has issues, Python. Solved! :) -- Russell Jurney twitter.com/rjurney russell.jur...@gmail.com datasyndrome.com
