yaooqinn opened a new pull request #24120: [SPARK-27183][YARN]YarnConfiguration in ApplicationMaster should be cluster-specific URL: https://github.com/apache/spark/pull/24120 ## What changes were proposed in this pull request? YarnConfiguration in ApplicationMaster should be cluster specified. In an kerberized yarn cluster with multiple hdfs federations, spark apps will write credentials files to a client determined hdfs cluster but not the yarn default hdfs of yarn cluster. You may see error like this while the application master updating tokens. ```scala java.lang.IllegalArgumentException: Wrong FS: hdfs://hz-cluster10/user/kyuubi/.sparkStaging/application_1552217598813_752210, expected: hdfs://hz-cluster7 at org.apache.hadoop.fs.FileSystem.checkPath(FileSystem.java:649) at org.apache.hadoop.hdfs.DistributedFileSystem.getPathName(DistributedFileSystem.java:194) at org.apache.hadoop.hdfs.DistributedFileSystem.listStatusInternal(DistributedFileSystem.java:788) at org.apache.hadoop.hdfs.DistributedFileSystem.access$700(DistributedFileSystem.java:106) at org.apache.hadoop.hdfs.DistributedFileSystem$18.doCall(DistributedFileSystem.java:853) at org.apache.hadoop.hdfs.DistributedFileSystem$18.doCall(DistributedFileSystem.java:849) at org.apache.hadoop.fs.FileSystemLinkResolver.resolve(FileSystemLinkResolver.java:81) at org.apache.hadoop.hdfs.DistributedFileSystem.listStatus(DistributedFileSystem.java:860) at org.apache.hadoop.fs.FileSystem.listStatus(FileSystem.java:1517) at org.apache.hadoop.fs.FileSystem.listStatus(FileSystem.java:1557) at org.apache.spark.deploy.SparkHadoopUtil.listFilesSorted(SparkHadoopUtil.scala:267) at org.apache.spark.deploy.yarn.security.AMCredentialRenewer.org$apache$spark$deploy$yarn$security$AMCredentialRenewer$$writeNewCredentialsToHDFS(AMCredentialRenewer.scala:210) at org.apache.spark.deploy.yarn.security.AMCredentialRenewer$$anon$1.run(AMCredentialRenewer.scala:107) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) ``` ## How was this patch tested? manually
