-------------------------------------
Summary: Enabled ControllerServices disabled on restart
Key: NIFI-2160
URL: https://issues.apache.org/jira/browse/NIFI-2160
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 0.7.0
Reporter: Brandon DeVries
Priority: Critical
Fix For: 0.7.0
As a result of the fix for NIFI-2032, previously enabled ControllerServices
become disabled after a restart if they are not referenced by another
component. However, we use a custom domain specific langauge that can
reference a controller service from a query defined as a custom processor's
property. This means that we use a number of controller service that are only
used in this way (i.e. are never directly referred to by another component).
Upon restart, these are now disabled causing issues with our flows.
I have not yet stepped through the new enableControllerServices() \[1\] method
to figure out exactly where the issue is coming from, but I wanted to get the
ticket out there and on the radar, as this breaks backwards compatibility on a
feature we heavily rely on.
