-------------------------------------
Resolution: Fixed
> Upgrade Impala operator Kopf dependency for Python 3.14 compatibility
> ---------------------------------------------------------------------
>
> Key: IMPALA-15204
> URL: https://issues.apache.org/jira/browse/IMPALA-15204
> Project: IMPALA
> Issue Type: Bug
> Reporter: Anubhav Jindal
> Assignee: Anubhav Jindal
> Priority: Critical
>
> *Description*
> {{IMPALA-14981}} moved the operator image to {{{}python:3.14.6-slim{}}}, but
> the operator can fail at runtime with: {{TypeError: 'NoneType' object does
> not support the context manager protocol}} during reconcile/logging paths.
> Root cause is a compatibility issue between older {{kopf}} ({{{}1.37.2{}}})
> and Python {{3.13+}} logging behavior.
> In older Kopf, a handler lock optimization can leave {{{}lock=None{}}}, while
> newer Python logging expects a context-manager lock in handler paths.
> *Proposed fix:*
> * Keep Python at {{3.14.6-slim}}
> * Upgrade operator dependency from {{kopf==1.37.2}} to a
> Python-3.14-compatible version ({{{}kopf==1.44.6{}}})
> * Keep {{kubernetes==30.1.0}} unchanged unless compatibility issues are found
> *Testing:*
> * Build operator image with Python {{3.14.6-slim}} + upgraded Kopf
> * Deploy on local k3d test cluster
> * Reconcile {{ImpalaCluster}} and verify operator reaches {{Ready}}
> * Verify no {{{}TypeError{}}}/{{{}NoneType{}}} logging crash in operator logs
> * Run existing operator/unit checks ({{{}test_main.py{}}}) and lint/critique
> checks
> *Impact:*
> * Restores runtime stability for operator on latest Python base image
> * Avoids reverting to older Python image while keeping dependency stack
> compatible
