Weijie Guo commented on FLINK-21943:
------------------------------------
In fact, for this kind of issue there is no need to create a JIRA ticket, a
hot-fix is more appropriate. Given that this ticket has been around for a long
time, let's leave it as it is.
> Redundant checkNotNull in Transformation#setResources
> -----------------------------------------------------
>
> Key: FLINK-21943
> URL: https://issues.apache.org/jira/browse/FLINK-21943
> Project: Flink
> Issue Type: Improvement
> Components: API / Core
> Affects Versions: 1.20.0
> Reporter: ZhangWei
> Priority: Minor
> Labels: pull-request-available
>
> In org.apache.flink.api.dag.Transformation#setResources(ResourceSpec
> minResources, ResourceSpec preferredResources),
> we have already checked that the parameters are not null by
> calling OperatorValidationUtils#validateMinAndPreferredResources.
> so it is not necessary to check again in setResources(
> ) , just assign the parameters.
