----------------------------------
Resolution: Feedback Received
Apache NiFi 1.x is no longer maintained and no new release is planned on the
1.x release line. Marking as resolved as part of a cleanup operation. Please
open a new one with an updated description if this is still relevant for NiFi
2.x.
> missing 'variable' element in FlowConfiguration.xsd > RootProcessGroupType
> ---------------------------------------------------------------------------
>
> Key: NIFI-6063
> URL: https://issues.apache.org/jira/browse/NIFI-6063
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.7.1
> Environment: Occured on Nifi 1.7.1, but in source code I see that
> it's still the case in nifi 1.9
> Reporter: Krzysztof Zarzycki
> Priority: Major
>
> It comes up as an error when starting Nifi with existing flow.xml.gz, that
> uses variable on root canvas:
> {code:java}
> [Reconnect to Cluster] o.a.n.c.StandardFlowSynchronizer Schema validation
> error parsing Flow Configuration at line 121803, col 59:
> cvc-complex-type.2.4.a: Invalid content was found starting with element
> 'variable'. One of '{controllerService, template}' is expected.{code}
> This is a probable cause of our issue to start nifi with existing flow.xml.gz
> in the cluster. We always need to delete it first before joining the cluster.
>
> As comment above RootProcessGroupType says in FlowConfiguration.xsd , it
> should be almost the same as ProcessGroupType (except input/output ports) so
> it should allow variable element too.
