When I run in spark-1.4 yarn-client mode, I throws the following Exception when trying to upload conf archive to viewfs:

The bug is easy to fix, we should pass the correct file system object to addResource. The similar issure is: https://github.com/apache/spark/pull/1483. I will attach my bug fix PR very soon.

The code in Client.scala is need to fix:

createConfArchive().foreach { file =>
      require(addDistributedUri(file.toURI()))
      val destPath = copyFileToRemote(dst, new Path(file.toURI()), replication)
      val destFs = FileSystem.get(destPath.toUri(), hadoopConf)  // here! use correct dest FileSystem
      distCacheMgr.addResource(destFs, hadoopConf, destPath, localResources, LocalResourceType.ARCHIVE,
        LOCALIZED_HADOOP_CONF_DIR, statCache, appMasterOnly = true)
    }
