------------------------------------
Summary: Template instantiation failure when multiple component
nar versions exist
Key: NIFI-5320
URL: https://issues.apache.org/jira/browse/NIFI-5320
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Affects Versions: 1.5.0
Reporter: Matthew Clarke
NiFi allows users to load multiple versions of the same component nar.
For example:
nifi-scripting-nar:1.2.0
nifi-scripting-nar:1.5.0
-
Once I have done this, if i try to instantiate a template to the canvas that
has a processor from this nar bundle that is neither of these versions
(nifi-scripting-nar:1.3.0), it will fail to instantiate the entire template.
-
This error is displayed to user:
"Multiple versions of org.apache.nifi.processors.script.ExecuteScript exist. No
exact match for org.apache.nifi:nifi-scripting-nar:1.3.0"
-
When there are not multiple nar versions, template instantiation works fine
since NiFi will automatically select the current processor version.
-
NiFi should allow a user to instantiate a template in such a scenario by either:
1. Prompt user to select which of the available versions to use during
instantiation.
2. Auto-select a new version (select most current version by default)
