dongjoon-hyun opened a new pull request, #57281: URL: https://github.com/apache/spark/pull/57281
### What changes were proposed in this pull request? Log only non-sensitive fields (`masterUrl`, `namespace`, `apiVersion`, `requestTimeout`, `connectionTimeout`, `trustCerts`) in the DEBUG log line of `SparkKubernetesClientFactory.createKubernetesClient`, instead of serializing the entire fabric8 `Config` object with a plain `ObjectMapper`. ### Why are the changes needed? `Config` holds the API server credentials, and a plain `ObjectMapper` applies no masking, so the previous line logged `oauthToken`, `clientKeyData`, `caCertData`, `clientCertData`, the basic-auth password, and the truststore password in cleartext. (`oauthToken` is annotated `@JsonIgnore`, but `@JsonIgnoreProperties(allowGetters = true)` on the class re-enables it via its getter.) `createKubernetesClient` runs on both the submission client and the driver, and driver logs are commonly collected and archived. ### Does this PR introduce _any_ user-facing change? No. DEBUG log content only. ### How was this patch tested? Pass the CIs. ### Was this patch authored or co-authored using generative AI tooling?
