If you don't want to allow nulls for particular fields, try a ValidateRecord processor using a schema that does not allow null values for the desired fields. I can't remember whether the "non-null" schema would be set on the Reader or Writer for ValidateRecord, but I believe it is the Reader. In that case, use the current schema (that allows nulls) for the Writer so the valid and invalid records can be output from the processor. Then you can send the "valid" relationship to the Elasticsearch processor, and handle the flowfiles/records on the "invalid" relationship however you choose.</P> Fri, 27 Apr 2018 03:02:41 GMT mburgess 2018-04-27T03:02:41Z
