You can use UpdateRecord and add a user-defined property something like /field3 set to concat( /field1, /field2 ). You can change /field3 to be whatever you want the output field name to be, and if you want to remove the other fields you can specify a schema in your Record Writer that only has the field(s) you want, such as:
{
"type": "record",
"name": "nifiRecord",
"namespace": "org.apache.nifi",
"fields": [{
"name": "field3",
"type": ["string", "null"]
}]
}
