[GitHub] [spark] dongjoon-hyun opened a new pull request, #42841: [SPARK-45095][CORE] Support `spark.master.rest.host`

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?
   
   No.
