Taylor Cressy updated SPARK-23983: ---------------------------------- Description: We should introduce a configuration for the spark UI to omit X-Frame-Options from the response headers if explicitly set. The X-Frame-Options header was introduced in *org.apache.spark.ui.JettyUtils* to prevent frame-related click-jacking vulnerabilities. This was addressed in: SPARK-10589 {code:java} val allowFramingFrom = conf.getOption("spark.ui.allowFramingFrom") val xFrameOptionsValue = allowFramingFrom.map(uri => s"ALLOW-FROM $uri").getOrElse("SAMEORIGIN") ... // In doGet response.setHeader("X-Frame-Options", xFrameOptionsValue) {code} The problem with this, is that we only allow the same origin or a singular host to present the UI with iframes. I propose we add a configuration that turns this off. Use Case: Currently building a "portal UI" for all things related to a cluster. Embedding the spark UI in the portal is necessary because the cluster is in the cloud and can only be accessed via an SSH tunnel - as intended. (The reverse proxy configuration {{*_spark.ui.reverseProxy_* could be used to simplify connecting to all the workers}}, but this doesn't solve handling multiple, unrelated, UIs through a single tunnel. Moreover, the host that our "portal UI" would reside on is not assigned a hostname and has an ephemeral IP address, so the *ALLOW-FROM* directive isn't useful in this case. Lastly, the current design does not allow for different hosts to be configured, i.e. *_spark.ui.allowFramingFrom_* _*hostname1,hostname2*_ is not a valid config.
