Deploy yarn meets incorrect LOCALIZED_CONF_DIR

We have implement a new Hadoop-compatible filesystem and run spark on it. The commands is:

./bin/spark-submit --class org.apache.spark.examples.SparkPi --master yarn --deploy-mode cluster --executor-memory 1G --num-executors 1 /home/hadoop/app/spark-2.3.0-bin-hadoop2.7/examples/jars/spark-examples_2.11-2.3.0.jar 10

The result is:

Exception in thread "main" org.apache.spark.SparkException: Application application_1522399820301_0020 finishe
d with failed status
at org.apache.spark.deploy.yarn.Client.run(Client.scala:1159)

We set log level to DEBUG and find:

As shown, _app.jar and spark_libs_ ‘s information are all correct. BUT _spark_conf_ has no port, scheme.

We explore the source code, addResource appears two times in Client.scala

val destPath = copyFileToRemote(destDir, localPath, replication, symlinkCache)
val destFs = FileSystem.get(destPath.toUri(), hadoopConf)
distCacheMgr.addResource(
destFs, hadoopConf, destPath, localResources, resType, linkname, statCache,
appMasterOnly = appMasterOnly)

 
val remoteConfArchivePath = new Path(destDir, LOCALIZED_CONF_ARCHIVE) val remoteFs = FileSystem.get(remoteConfArchivePath.toUri(), hadoopConf) sparkConf.set(CACHED_CONF_ARCHIVE, remoteConfArchivePath.toString()) val localConfArchive = new Path(createConfArchive().toURI()) copyFileToRemote(destDir, localConfArchive, replication, symlinkCache, force = true, destName = Some(LOCALIZED_CONF_ARCHIVE)) // Manually add the config archive to the cache manager so that the AM is launched with // the proper files set up. 
distCacheMgr.addResource( remoteFs, hadoopConf, remoteConfArchivePath, localResources, LocalResourceType.ARCHIVE, LOCALIZED_CONF_DIR, statCache, appMasterOnly = false)

As shown in the source code, the destPaths are differently constructed. And this is confirmed by self added debug log
