             Summary: HandleHTTPResponse processor exceptions when connection is closed
                 Key: NIFI-1814
                 URL: https://issues.apache.org/jira/browse/NIFI-1814
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 0.6.1
         Environment: Centos 6
            Reporter: Sam Hjelmfelt


If a HTTP connection is closed before a response is sent, the HandleHTTPResponse processor will throw an exception, yield due to failure, then try processing the rest of the events. If multiple errors happen at once, this compounded delay can cause cascading issues as the other connections timeout and close.

Instead, the exception should be caught and the flowfile should go to the error relationship. A closed connection should not fail the processor, but instead fail the flowfile.

Exception:
HandleHttpResponse[id=cca1576b-5841-3fc1-b05a-5fd0f4853cb7] failed to process session due to org.apache.nifi.processor.exception.FlowFileAccessException: Failed to export StandardFlowFileRecord[uuid=febaedb5-4830-46b7-b0f9-71b453a4743c,claim=StandardContentClaim [resourceClaim=StandardResourceClaim[id=1461688143223-3, container=contS2R1, section=3], offset=999718, length=999718],offset=0,name=1628795866820216,size=999718] to HttpOutput@28849fc{OPEN} due to org.eclipse.jetty.io.EofException: org.apache.nifi.processor.exception.FlowFileAccessException: Failed to export StandardFlowFileRecord[uuid=febaedb5-4830-46b7-b0f9-71b453a4743c,claim=StandardContentClaim [resourceClaim=StandardResourceClaim[id=1461688143223-3, container=contS2R1, section=3], offset=999718, length=999718],offset=0,name=1628795866820216,size=999718] to HttpOutput@28849fc{OPEN} due to org.eclipse.jetty.io.EofException
