---------------------------------------
Summary: Verify Configuration Throws Exception in List Azure
Processors
Key: NIFI-14865
URL: https://issues.apache.org/jira/browse/NIFI-14865
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 2.5.0
Reporter: David Handermann
Assignee: David Handermann
The {{ListAzureDataLakeStorage}} and {{ListAzureBlobStorage_v12}} Processors
extend from a class hierarchy that includes the {{AbstractListProcessor}},
which supports configuration verification. The {{AbstractListProcessor}}
implements the verify method and calls the {{performListing}} method with a
Listing Mode, but the List Azure Processors do not check the Listing Mode when
determining the Azure Client Factory that should be used. As a result, the
Client Factory is null because the current implementations depend on this being
initialized when the framework schedules the Processor. Checking the Listing
Mode and optionally creating a Client Factory for the configuration
verification should allow verification to work as expected.
