Description

When a field specified in schema is missing and we call avro::encode on the data. It throws an exception, which is as expected. But the issue is with the error message. It comes the other way round.

Schema:

{
 "type" : "record",
 "name" : "userInfo",
 "fields" : [
    { "name" : "id", "type" : "int"},
    { "name" : "fullName", "type" : "string" }
 ]
}

The generic datum to be encoded has no "id" provided. There is an empty GenericDatum for that field. Here is the excetion that is thrown:

avro::Exception caught: Invalid operation. Expected: Null got Int

The exception message should have been 
avro::Exception caught: Invalid operation. Expected: Int got Null
