…rn.am.tokenConfRegex' to support renewing delegation tokens in a multi-cluster environment (apache#1300) This adds a new config `spark.yarn.am.tokenConfRegex` which is similar to `mapreduce.job.send-token-conf` introduced via [YARN-5910](https://issues.apache.org/jira/browse/YARN-5910). It is used for YARN AM to pass Hadoop configs, such as `dfs.nameservices`, `dfs.ha.namenodes.`, `dfs.namenode.rpc-address.`, etc, to RM for renewing delegation tokens. [YARN-5910](https://issues.apache.org/jira/browse/YARN-5910) introduced a new config `mapreduce.job.send-token-conf` which can be used to pass a job's local configuration to RM which uses them when renewing delegation tokens. A typical use case is when a YARN cluster needs to talk to multiple HDFS clusters, where the RM may not have all the configs (e.g., `dfs.nameservices`, `dfs.ha.namenodes.<nameservice>.*`, `dfs.namenode.rpc-address`) to connect to these clusters when renewing delegation tokens. In this case, the clients can use the feature to pass their local HDFS configs to RM. Yes, a new config `spark.yarn.am.tokenConfRegex` will be introduced to Spark users. By default it is disabled. It seems difficult to come up with a unit test for this. I manually tested it against a YARN cluster with Hadoop version 3.x and it worked as expected. ``` $SPARK_HOME/bin/spark-shell --master yarn \ --deploy-mode client \ --conf spark.driver.extraClassPath="${HADOOP_CONF_DIR}" \ --conf spark.executor.extraclasspath="${HADOOP_CONF_DIR}" \ --conf spark.yarn.am.tokenConfRegex="^dfs.nameservices$|^dfs.namenode.rpc-address.*$|^dfs.ha.namenodes.*$|^dfs.client.failover.proxy.provider.*$|^dfs.namenode.kerberos.principal|^dfs.namenode.kerberos.principal.pattern" \ --conf spark.yarn.access.hadoopFileSystems="<HDFS_URI>" ``` Closes apache#34635 from sunchao/SPARK-37205.
