question Re: add field to csv file based on other field value in Support Questions https://community.cloudera.com/t5/Support-Questions/add-field-to-csv-file-based-on-other-field-value/m-p/177555#M139803 Hi @Shu, thanks for the detailed reply. But I would prefer using Record-based processors (such as SplitRecord and UpdateRecord) since CSV is considered record-based as well. But I am faced with a problem and can't figure it out. I would appreciate if you could suggest a solution or point me in the right direction.Here is what I have done:create sample csv file<PRE>name,age,height,weight,school james, 19, 173, 56, NY jake, 20, 177, 62, MD sam, 21, 160, 55, KN Mike, 24, 170, 64, MM</PRE>created AvroSchemaRegistry<PRE>{ "name": "origFormatName", "namespace": "someFields", "type": "record", "fields": [ { "name": "name", "type": "string" }, { "name": "age", "type": "int" }, { "name": "height", "type": "int" }, { "name": "weight", "type": "int" }, { "name": "school", "type": "string" } ] } </PRE>Then CSVReader and CSVRecordSetWriter contoller services (referencing the same AvroSchema)Then using UpdateAttribute I update the file's attribute by adding property schema.name=thename This successfully adds the attribute. Afterwards, I use SpliteRecord and set the Record Reader and Record Writer property as appropriate (Records Per Split = 1). It does split the file into 4 records as expected. Then I use UpdateRecord. And again set Record Reader and Record Writer. And for Replacement Value Strategy I set value to Literal Value for simplicity. Then add a property as below<PRE>/fields[2]/height = 2222</PRE>Then I get the 4 records (as expected) coming from UpdateRecord. But they are all size=0. I can't understand why would it return size 0.Any help would be appreciated.Thanks. Thu, 05 Oct 2017 21:49:05 GMT samgoldopamp 2017-10-05T21:49:05Z
