dongjoon-hyun opened a new pull request, #42841: URL: https://github.com/apache/spark/pull/42841
### What changes were proposed in this pull request? This PR aims to support a new configuration `spark.master.rest.host` to allow REST Server to choose a host to listen. ### Why are the changes needed? In K8s environment, it's difficult to use `port-forward` because the AS-IS Spark REST Server only listens the podIP and not 127.0.0.1. K8s port-forwarding only works with 127.0.0.1. ``` $ SPARK_NO_DAEMONIZE=1 SPARK_MASTER_OPTS="-Dspark.master.rest.enabled=true -Dspark.master.rest.host=0.0.0.0" sbin/start-master.sh ``` ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Manually start the REST API. ``` $ SPARK_NO_DAEMONIZE=1 SPARK_MASTER_OPTS="-Dspark.master.rest.enabled=true -Dspark.master.rest.host=0.0.0.0" sbin/start-master.sh ``` Connect with both IPs (public and 127.0.0.1) on the machine. ``` $ curl -v http://127.0.0.1:6066/v1/submissions/status/0 ``` ### Was this patch authored or co-authored using generative AI tooling?
