             Summary: HandleHttpRequest doesn't correctly handle failures to register requests
                 Key: NIFI-1913
                 URL: https://issues.apache.org/jira/browse/NIFI-1913
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Joseph Percivall
            Assignee: Joseph Percivall


While looking at this[1] stack overflow question I came across the fact that HandleHttpRequest doesn't properly handle the flowfiles when there is a failure to register[2]. The created FlowFile should be removed just like it is done here[3]. This lack of removal causes a FlowFileHandlingException to occur when the context map fails to register the flowfile.

The fix is simply adding "session.remove(flowFile);" to the "if (!registered)" block.
