Joe Witt commented on NIFI-4315:
--------------------------------
Surely someone can try/test it. But keep in mind there is no guarantee a
shutdown hook will run so as noted in the logback jira this is a partial
solution.
> Upgrade to newer version of logback

> Key: NIFI-4315
> URL: https://issues.apache.org/jira/browse/NIFI-4315
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 1.3.0
> Reporter: Aldrin Piri
> Priority: Major
>
> There are some bugs outstanding with logback that can cause compression to
> fail in some environments (was able to recreate in Windows and OS X),
> seemingly related to the current outstanding issue:
> https://jira.qos.ch/browse/LOGBACK-1162
> This will also cause the given set of files to grow beyond their bounds of a
> specified totalSizeCap if one is provided.
> Steps I used to create this comprised:
> * Using a simple flow that generates flow files and terminates them at an
> update attribute is sufficient.
> * Adjust logback to have DEBUG level for the root logger.
