Looks good, will merge
> If 0-byte FlowFiles are load balanced, can result in content claim not being
> cleaned up
> ---------------------------------------------------------------------------------------

> Key: NIFI-5771
> URL: https://issues.apache.org/jira/browse/NIFI-5771
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Mark Payne
> Priority: Critical
> Fix For: 1.9.0
>
>
> To replicate, create two separate Flows:
> GenerateFlowFile (File Size 800 KB) -> UpdateAttribute [auto-terminate]
> GenerateFlowFile (FileSize 0 B) -> UpdateAttribute [auto-terminate]
> On the second one, that is generating 0-byte flowfiles, configure the
> Connection to Load Balance (Round Robin is easiest).
> Start both flows.
> After a minute or two, stop the GenerateFlowFile processors; let the
> flowfiles finish being processed by UpdateAttribute.
> Now, wait for the FlowFile Repository to checkpoint. At this point, the
> content claim should be cleaned up and delete/archive any content claims
> (with the exception of a few claims that are still 'writable'). However, some
> claims are still sticking around when they shouldn't.
