----------------------------------
Summary: Deploy yarn meets incorrect LOCALIZED_CONF_DIR
Key: SPARK-23843
URL: https://issues.apache.org/jira/browse/SPARK-23843
Project: Spark
Issue Type: Bug
Components: Deploy
Affects Versions: 2.3.0
Environment: spark-2.3.0-bin-hadoop2.7
Reporter: zhoutai.zt
We have implement a new Hadoop-compatible filesystem and run spark on it. The
commands is:
{quote}./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
{quote}
The result is:
{quote}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)
{quote}
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
{code:java}
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)
{code}
{code:java}
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)
{code}
As shown in the source code, the destPaths are differently constructed. And
this is confirmed by self added debug log
