Title
Body
Suppose I’ve got the following schema: { "name" : "Profile", "type" : "record", "fields" : [ { "name" : "firstName", "type" : "string" }, { "name" : "address", "type" : { "type" : "record", "name" : "AddressUSRecord", "fields" : [ { "name" : "address1" , "type" : "string" }, { "name" : "address2" , "type" : "string" }, { "name" : "city" , "type" : "string" }, { "name" : "state" , "type" : "string" }, { "name" : "zip" , "type" : "int" }, { "name" : "zip4", "type": "int" } ] } } ] } I’m using a GenericRecord to represent each Profile that gets created. To add a firstName , it’s easy to do the following: Schema sch = Schema.parse(schemaFile); DataFileWriter<GenericRecord> fw = new DataFileWriter<GenericRecord>(new GenericDatumWriter<GenericRecord>()).create(sch, new File(outFile)); GenericRecord r = new GenericData.Record(sch); r.put(“firstName”, “John”); fw.append(r); But how would I set the city , for example? How do I represent the key as a string that the r.put method can understand?
