Colin Dean created NIFI-5579:
--------------------------------
Summary: Allow ExecuteGroovyScript to take a SQL property that is
a DBCPConnectionPoolLookup
Key: NIFI-5579
URL: https://issues.apache.org/jira/browse/NIFI-5579
Project: Apache NiFi
Issue Type: Wish
Components: Core Framework
Affects Versions: 1.7.1, 1.7.0
Environment: Any
Reporter: Colin Dean
I would like to reference a {{DBCPConnectionPoolLookup}} controller service
from within an {{ExecuteGroovyScript}} processor. If I create a property
{{SQL.lookup}} and set its value to an existing {{DBCPConnectionPoolLookup}}
controller service, when I start the processor, it fails immediately because
the creation of the "connection" by the {{DBCPConnectionPoolLookup}} controller
service fails because it was not passed the expected {{database.name}}
attribute.
