-------------------------------------------
Summary: Change 'App Config File' property to external resource in
Box processors
Key: NIFI-10597
URL: https://issues.apache.org/jira/browse/NIFI-10597
Project: Apache NiFi
Issue Type: Improvement
Components: Extensions
Reporter: Zsihovszki Krisztina
Fix For: 1.19.0
The Box app configuration can be specified as JSON file for Box processors, see
"app-config-file" in JsonConfigBasedBoxClientService.
Google processors use GCPCredentialsControllerService which includes a similar
property for the configuration file in JSON format: "service-account-json-file".
The "service-account-json-file" property uses
{code:java}
.identifiesExternalResource(ResourceCardinality.SINGLE, ResourceType.FILE){code}
in its PropertyDescriptor,
while "app-config-file" in Box case uses
{code:java}
.addValidator(StandardValidators.FILE_EXISTS_VALIDATOR){code}
It'd be useful to replace the StandardValidators.FILE_EXISTS_VALIDATOR usage
with
identifiesExternalResource in the Box case. It contains the same check for file
existence and also checks file accessbility, does not allow to specify
directory instead of file.
