I want to convert a csv file to a parquet which has numeric column names (1,2,3 etc). I am using *convert record processor* in which I am using a csv-reader as the reader and inferring the schema and using writer as parquet-writer. I have observed that nifi replaces my column names with '_' (underscores) which I believe is to make it avro valid.(AvroTypeUtils.java) But this is making all my column names '_'. Is there a way where I can prepend an underscore to column names (_1,_2,_3, etc) instead of replacing it with underscore ?
