Márton Balassi commented on FLINK-29206:
----------------------------------------
Hi [~tashoyan],
Thanks for bringing this up, these are in fact the configuration values of the
operator itself. The helm property value being named defaultConfiguration
certainly makes a wrong impression. Let me think about this and come back to
you.
> Default Flink configuration contains irrelevant settings
> --------------------------------------------------------
>
> Key: FLINK-29206
> URL: https://issues.apache.org/jira/browse/FLINK-29206
> Project: Flink
> Issue Type: Bug
> Components: Kubernetes Operator
> Affects Versions: 1.15.2
> Reporter: Arseniy Tashoyan
> Priority: Major
>
> The default configuration of a FlinkDeployment contains the following
> settings:
> {code:yaml}
> kubernetes.operator.metrics.reporter.slf4j.interval: 5 MINUTE
> kubernetes.operator.metrics.reporter.slf4j.factory.class:
> org.apache.flink.metrics.slf4j.Slf4jReporterFactory
> kubernetes.operator.reconcile.interval: 15 s
> kubernetes.operator.observer.progress-check.interval: 5 s
> {code}
>
> These settings are specific to Flink Kubernetes Operator itself, but not to
> Flink applications that the Operator runs. Although these settings most
> probably do not make any influence on a Flink application (they are just
> ignored), but the configuration is misleading. It would be better to remove
> these settings from the default configuration of a Flink application.
> Actually these settings come from the _defaultConfiguration_ section of the
> file {_}helm/flink-kubernetes-operator/values.yaml{_}:
> {code:yaml}
> defaultConfiguration: ...
> flink-conf.yaml: |+
> # TODO Remove these Operator-specific settings - they are irrelevant to
> Flink apps
> kubernetes.operator.metrics.reporter.slf4j.factory.class:
> org.apache.flink.metrics.slf4j.Slf4jReporterFactory
> kubernetes.operator.metrics.reporter.slf4j.interval: 5 MINUTE
> kubernetes.operator.reconcile.interval: 15 s
> kubernetes.operator.observer.progress-check.interval: 5 s
> {code}
> This piece of configuration is misleading - is it the configuration of the
> Operator itself or the configuration of applications started by the Operator?
