Xing Lin commented on HDFS-16816: --------------------------------- /user dir may not be writable for any regular user. In that case, assume userA dir is not created in /user, when userA calls moveToTrash(/dir/file), it will hit the permission denied error when it is trying to create dir /user/userA/.Trash/Current/dir, because userA does not have write permission for /user. > RBF: auto-create user home dir for trash paths by router > -------------------------------------------------------- > > Key: HDFS-16816 > URL: https://issues.apache.org/jira/browse/HDFS-16816 > Project: Hadoop HDFS > Issue Type: Improvement > Components: rbf > Reporter: Xing Lin > Assignee: Xing Lin > Priority: Minor > Labels: pull-request-available > > 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). -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
