----------------------------------------
Summary: Provenance is blank is
`nifi.provenance.repository.compress.on.rollover` is set to `true`
Key: NIFI-7893
URL: https://issues.apache.org/jira/browse/NIFI-7893
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.12.1, 1.11.4
Environment: Docker 19.03.13
Image: apache/nifi:1.12.1
Python: nipyapi: 0.14.1
Reporter: Daniel Khodabakhsh
On Nifi 1.11.4 and 1.12.1, I intermittently am unable to view the provenance in
the UI and through the `nipyapi` python library.
Checking the logs, I get the following message:
{color:#FF0000}2020-10-06 22:12:39,789 INFO [Timer-Driven Process Thread-10]

Setting `nifi.provenance.repository.compress.on.rollover=false` fixes this.
Here's a copy of all my `nifi.provenance.repository` settings from
