Matt Burgess commented on NIFI-2359:


What about the case where you only want to convert some strings into numbers 
but not all of them, such as zip codes?

There is a workaround if you know which attributes will be written to JSON: 
After AttributesToJSON you can use ConvertRecord with a JsonTreeReader (with a 
schema specifying all fields as strings) and a JsonRecordSetWriter (with the 
desired output schema).

Instead of rolling you own isNumber method, why not use NumberUtils.isNumber?
