Worked on updating the apache/spark repository’s documentation to align with Kubernetes security changes, focusing on the deprecation of Pod Security Policies in version 1.25. The contribution involved removing outdated references and guiding users toward the Pod Security Admission Controller, reducing the risk of misconfiguration and support issues. This update was delivered entirely in Markdown, emphasizing clear communication of security best practices for Spark’s Kubernetes integration. The work demonstrated attention to evolving platform requirements and collaborative review, ensuring that Spark documentation remains accurate and relevant for users managing security in modern Kubernetes environments without introducing any functional code changes.
