Mark Payne commented on NIFI-7469:
----------------------------------
Thanks for reporting this [~Steto84]. I updated the title of the Jira to be a
bit more encompassing.
The problem occurs any time a Processor receives an incoming FlowFile that is 0
bytes, then modifies the content of a FlowFile by writing zero bytes. In this
case, the framework gets confused because both versions of the content appear
to be the same, but they are not.
> Processors that write zero-byte content may cause Content Repository Cleanup
> to fail

> Key: NIFI-7469
> URL: https://issues.apache.org/jira/browse/NIFI-7469
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.10.0, 1.11.0, 1.11.1, 1.11.4
> Environment: Windows 10, ubuntu 18.04
> Reporter: Stefano Piana
> Priority: Major
> Attachments: ReplaceTextBug.xml
>
>
> Trying to replace an empty flowfile with and empty value may cause the
> content repository
> to accumulate and not being correctly cleaned up until the next NiFi restart.
> this behaviour has been observed on nifi 1.10+
> to reproduce the problem just generate a flowfile that has some content, then
> replace the content with the ReplaceText processor setting it to always
> replace and set the replacement to empty string. Copy the ReplaceText
> processor and try replacing the content with an empty string again, then just
> use any processor to drain the flowfiles. This will cause the content
> repository to accumulate and stop being correctly cleaned up.
> here attached a simple flow that reproduces the problem.
