   I think what @zuston mentioned here is the case, for example:
   
   * user A launched a Spark application, and send shuffle data to shuffle server.
   * Shuffle server should write shuffle data with "user A" into HDFS.
   * Reduce tasks (launched by user A) could read shuffle data in HDFS with user A.
   
   Otherwise, user A may not have the permission to ready shuffle data written by shuffle server (another user) if it it is not owned by A.
   
   I'm not sure if I understand correctly or not? @zuston
