我在hadoop distcp中面临以下问题，任何建议或帮助都将不胜感激。
我正在尝试将数据从google云平台复制到amazons3
1） 当我们有多个文件要从源复制到目标时（这很好）

val sourcefile : String = "gs://XXXX_-abc_account2621/abc_account2621_click_20170616*.csv.gz [Multiple files to copy (we have * in the file name)]

  Output: S3://S3bucketname/xxx/xxxx/clientid=account2621/date=2017-08-18/
  Files in above path
  abc_account2621_click_2017061612_20170617_005852_572560033.csv.gz
  abc_account2621_click_2017061616_20170617_045654_572608350.csv.gz
  abc_account2621_click_2017061622_20170617_103107_572684922.csv.gz
  abc_account2621_click_2017061623_20170617_120235_572705834.csv.gz

2） 当我们只有一个文件要从源复制到目标时（问题）

val sourcefile : String = "gs://XXXX_-abc_account2621/abc_account2621_activity_20170618_20170619_034412_573362513.csv.gz

   Output:S3://S3bucketname/xxx/xxxx/clientid=account2621/ 
   Files in above path 
   date=2017-08-18 (Directory replace with file content and it doesn't have file type)

代码：

def main(args: Array[String]): Unit = {

 val Array(environment,customer, typesoftables, clientid, filedate) = args.take(5)

 val S3Path: String = customer + "/" + typesoftables + "/" + "clientid=" + clientid + "/" + "date=" + filedate + "/"

 val sourcefile : String = "gs://XXXX_-abc_account2621//abc_account2621_activity_20170618_20170619_034412_573362513.csv.gz"

 val destination: String = "s3n://S3bucketname/" + S3Path

 println(sourcefile)
 println(destination)

 val filepaths: Array[String] = Array(sourcefile, destination)  

 executeDistCp(filepaths)

 }

 def executeDistCp(filepaths : Array[String]) {
val conf: Configuration = new Configuration()

conf.set("fs.gs.impl", "com.google.cloud.hadoop.fs.gcs.GoogleHadoopFileSystem")
conf.set("fs.AbstractFileSystem.gs.impl","com.google.cloud.hadoop.fs.gcs.GoogleHadoopFS")
conf.set("google.cloud.auth.service.account.enable", "true")
conf.set("fs.gs.project.id", "XXXX-XXXX")
conf.set("google.cloud.auth.service.account.json.keyfile","/tmp/XXXXX.json")
conf.set("fs.s3n.awsAccessKeyId", "XXXXXXXXXXXX")
conf.set("fs.s3n.awsSecretAccessKey","XXXXXXXXXXXXXX")    
conf.set("mapreduce.application.classpath","$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/*,$HADOOP_MAPRED_HOME/share/hadoop/mapreduce/lib/*

conf.set("HADOOP_CLASSPATH","$HADOOP_CLASSPATH:/tmp/gcs-connector-latest-hadoop2.jar")

val outputDir: Path = new Path(filepaths(1))
outputDir.getFileSystem(conf).delete(outputDir, true)

val distCp: DistCp = new DistCp(conf,null)
ToolRunner.run(distCp, filepaths)

}
