Subject convert empty strings to null
Date Mon, 26 Jan 2015 18:05:24 GMT
My input file is a json file. I am loading that into a staging table. Then
i am parsing the json using hive (Lateral view and json_tuple) and writing
to a final avro table. My issue is some json values have empty strings. I
want those empty strings to display as null..
what is the best way to achieve this??
