             Summary: Exception thrown by StandardProcessSession.exportTo implies issues reading from repository
                 Key: NIFI-1866
                 URL: https://issues.apache.org/jira/browse/NIFI-1866
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
            Reporter: Mark Payne
            Assignee: Mark Payne
             Fix For: 0.7.0


When calling ProcessSession.exportTo, if unable to write to the OutputStream provided, we end up with a FlowFileAccessException, rather than IOException. This implies that we were unable to access the ContentRepository, but this is not accurate. We need to ensure that we throw the appropriate Exception here so that Processors that cause ProcessException are able to handle the Exception properly
