### What changes were proposed in this pull request? This PR aims to add `checkValues` to `spark.master.ui.decommission.allow.mode` configuration to validate the setting as early as possible. ### Why are the changes needed? To prevent misconfigurations. **BEFORE (NO WARNING)** ``` $ SPARK_NO_DAEMONIZE=1 SPARK_MASTER_OPTS="-Dspark.master.ui.decommission.allow.mode=ALLOWS" sbin/start-master.sh ... 24/01/27 22:14:25 INFO Master: I have been elected leader! New state: ALIVE ``` **AFTER (FAILURE)** ``` $ SPARK_NO_DAEMONIZE=1 SPARK_MASTER_OPTS="-Dspark.master.ui.decommission.allow.mode=ALLOWS" sbin/start-master.sh ... java.lang.IllegalArgumentException: The value of spark.master.ui.decommission.allow.mode should be one of ALLOW, LOCAL, DENY, but was ALLOWS ``` ### Does this PR introduce _any_ user-facing change? Yes However, this prevents a user to start `Spark Master` with misconfiguration. So, it happens only at the first start of the migrated Spark master installation. So, this is going to be solved before running Spark Master successfully first time. ### How was this patch tested? Manually. ### Was this patch authored or co-authored using generative AI tooling?
