jiangzho opened a new pull request, #171: URL: https://github.com/apache/spark-kubernetes-operator/pull/171
### What changes were proposed in this pull request? This PR sets Content-Type header for Prometheus handler to make it compatible with Prometheus v3 ### Why are the changes needed? Prometheus v3 will fail the scrape if the Content-Type header is not present in response and the fallback scrape protocol is not configured. Therefore we'd configure the headers properly. Please also refer https://prometheus.io/docs/prometheus/latest/migration/#scrape-protocols ### Does this PR introduce any user-facing change? No ### How was this patch tested? Tested via CI and local set up for Prometheus v3, via steps: * Deploy Prometheus v3 in k8s cluster, with default configuration (no fallback_scrape_protocol configured) * Deploy Spark Operator in cluster * Prometheus v3 is able to successfully scrape operator metrics ### Was this patch authored or co-authored using generative AI tooling?
