--------------------------------
Summary: Attribute values are converted to sensitive values after
NiFi upgrades, when custom nars are used
Key: NIFI-11468
URL: https://issues.apache.org/jira/browse/NIFI-11468
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: John Wise
We've recently started experiencing an issue where the attribute values in ~1/4
to 1/3 of the processors in a given flow are changed from plain text to
sensitive values. Those values are then non-recoverable, and must be manually
deleted and re-created.
We narrowed this down to some dependencies on previous NiFi versions in our
custom nars. If I exclude the custom nars until after the upgrade is done &
the NiFi service is run for the first time after the upgrade, then the all of
the standard NiFi processor upgrade versions as expected.
Once I re-add the custom nars, those with previous NiFi dependencies will
convert attribute values from plain text to sensitive values. This seems to be
a bug in the processor version upgrade logic.
