David Handermann resolved NIFI-1983.
------------------------------------
Resolution: Won't Fix
NIFI-6018 deprecated PostHTTP in favor of InvokeHTTP.
> Add flag to disable PostHttp's two phase commit
> -----------------------------------------------
>
> Key: NIFI-1983
> URL: https://issues.apache.org/jira/browse/NIFI-1983
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Reporter: Edgardo Vega
> Priority: Critical
>
> By default PostHttp interprets the response, and based on a series of
> conditions can intentionally issue a delete. This delete action is good some
> environments there were timeouts that would occur quite frequently between
> PostHTTP / ListenHTTP and this resulted in quite a lot of data duplication.
> In environments where this is not an issue or where data duplication is okay
> this causes problems with certain load balancers such as AWS ELB.
> Having a flag to disable this feature would be useful in getting Nifi to work
> better in AWS in general.
