> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.8.0
> Reporter: Aaron Leon
> Priority: Major
>
> The PostHTTP processor performs a HEAD Request to the specified REST endpoint
> to check if the endpoint accepts FlowFiles. This check should NOT occur if
> "Send As FlowFile" is set to false; this will throw a 404 exception if the
> endpoint does not accept HEAD requests.
> Encountered while using PostHTTP processor to send a POST request to /_bulk
> endpoint of Elasticsearch 5.3
