Tony Kurc commented on NIFI-26:
-------------------------------
Long standing bug. Regardless of whether the scenario can be replicated, it
seems exception handling needs a review on that processor.
> Bug in PostHTTP triggered by DNS issues
> ---------------------------------------
>
> Key: NIFI-26
> URL: https://issues.apache.org/jira/browse/NIFI-26
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Reporter: Mark Payne
> Priority: Minor
>
> After a successful POST, if doing 2-phase commit, we loop indefinitely until
> we get a response from the server or the user stops the processors. If DNS
> issues pop up or a firewall, we instead get IOException, and we loop
> indefinitely, destroying system resources.
> This issue is the result of continually trying to delete the HOLD until we
> successfully receive an HTTP Response from the Server. We should instead
> change the logic to retry only some configurable number of times and wait 1
> second in between retries.
