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 -- This is an automated message from the Apache Git Service.
