> Error in Controller Service with dynamic property in Cluster environment
> ------------------------------------------------------------------------
>
> Key: NIFI-5034
> URL: https://issues.apache.org/jira/browse/NIFI-5034
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.4.0, 1.5.0
> Reporter: Mark Bean
> Priority: Major
>
> Environment: Controller Service provides a lookup service to other Controller
> Services. To configure, the lookup CS uses dynamic properties where the key
> is an arbitrary name and the value is an existing Controller Service.
> In a cluster environment only (this is not an issue for stand-alone
> environment), the UI displays returns "An unexpected error has occurred" due
> to http 500 return code. This occurs when attempting to configure the
> controller service with the dynamic property. Additionally, it throws the
> same error (http 500) when trying to configure the process group owning the
> lookup controller service. (The property on the controller service is created
> despite the 500 return code.)
> Diving into the code a bit, the fact of being a "cluster only" issue is in
> FlowResource.java:400.
> if (isReplicateRequest()) {
> return replicate(HttpMethod.GET);
> }
> The problem is the return value is null even when controller services exist.
> Ultimately, ApplicationResource.java:288 parses a map of http servlet
> parameters. The controller service should be a parameter. Yet, this map is
> empty.
> for (final Map.Entry<String, String[]> entry :
> httpServletRequest.getParameterMap().entrySet()) \{ ... }
> This problem is preventing the implementation of a Controller Service with
> dynamic properties (whose property values are other Controller Services) in a
> cluster environment.
