[jira] [Created] (NIFI-6242) PutFileTransfer generating incorrect provenance events

Brandon DeVries created NIFI-6242:
-------------------------------------

             Summary: PutFileTransfer generating incorrect provenance events
                 Key: NIFI-6242
                 URL: https://issues.apache.org/jira/browse/NIFI-6242
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 1.9.2
            Reporter: Brandon DeVries


PutFileTransfer transfers a (configurable size) batch of FlowFiles.  However, the provenance SEND event generated [1] uses the hostname evaluated from the first FlowFile of the batch.  If the hostname is a hardcoded string, there's no issue... but if the hostname uses Expression Language, the generated provenance events will be incorrect (and very confusing).
