Yiqun Lin updated HDFS-12895: ----------------------------- Labels: RBF incompatible (was: RBF) Release Note: Mount tables support ACL, The users won't be able to modify their own entries (we are assuming these old (no-permissions) mount table with owner:superuser, group:supergroup, permission:755 as the default permissions). The fix way is login as superuser to modify these mount table entries. > RBF: Add ACL support for mount table > ------------------------------------ > > Key: HDFS-12895 > URL: https://issues.apache.org/jira/browse/HDFS-12895 > Project: Hadoop HDFS > Issue Type: Sub-task > Affects Versions: 3.0.0-alpha3 > Reporter: Yiqun Lin > Assignee: Yiqun Lin > Labels: RBF, incompatible > Fix For: 3.1.0, 2.10.0, 2.9.1, 3.0.1 > > Attachments: HDFS-12895-branch-2.001.patch, HDFS-12895.001.patch, > HDFS-12895.002.patch, HDFS-12895.003.patch, HDFS-12895.004.patch, > HDFS-12895.005.patch, HDFS-12895.006.patch, HDFS-12895.007.patch > > > Adding ACL support for the Mount Table management. Following is the initial > design of ACL control for the mount table management. > Each mount table has its owner, group name and permission. > The mount table permissions (FsPermission), here we use > {{org.apache.hadoop.fs.permission.FsPermission}} to do the access check: > # READ permission: you can read the mount table info. > # WRITE permission: you can add remove or update this mount table info. > # EXECUTE permission: This won't be used. > The add command of mount table will be extended like this > {noformat} > $HADOOP_HOME/bin/hdfs dfsrouteradmin [-add <source> <nameservice> > <destination> [-owner <owner>] [-group <group>] [-mode <mode>]] > {noformat} > *<mode> is UNIX-style permissions for the mount table. Permissions are > specified in octal, e.g. 0755. By default, this is set to 0755*. > If we want update the ACL info of specfied mount table, just execute add > command again. This command not only adding for new mount talle but also > updating mount table once it finds given mount table is existed. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
