             Summary: JoltTransformRecord should not only take schema from first record
                 Key: NIFI-15209
                 URL: https://issues.apache.org/jira/browse/NIFI-15209
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Jordan Sammut


There looks to be an issue with the JoltTransformRecord processor, whereby the schema is only being determined using the first record in a batch. This in turn might result in inconsistencies with the Jolt and output incorrect results. 

The following is a simple example:


[ \{ "operation": "shift", "spec": { "test_field": { "": "TRASH", "*": { "$": "value.test_field" } } } } ]
 
Taking the above jolt, and the following input:
{ "test_field" : "" } \{ "test_field" : "value2" }
 
is resulting in the following result which should not be the case:
{"remove":null} \{"remove":null}
