> In RBF, trash files are moved to trash root under user's home dir at the corresponding namespace/namenode where the files reside. This was added in HDFS-16024. When the user home dir is not created before-hand at a namenode, we run into permission denied exceptions when trying to create the parent dir for the trash file before moving the file into it. We propose to enhance Router, to auto-create a user home's dir at the namenode for trash paths, using router's identity (which is assumed to be a super-user).
