[NIFI-1814] HandleHTTPResponse processor exceptions when connection is closed

• Type: Bug
• Status: Resolved
• Priority: Blocker
• Resolution: Fixed
• Affects Version/s: 0.6.1
• Component/s: Core Framework
• Environment: Centos 6

Description

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
