Aaron T. Myers commented on HDFS-4230: -------------------------------------- I think we should probably make listing all the snapshottable directories in the FS a super-user only privilege, since there may be snapshottable directories that ordinary users are not even aware exist, and whose existence they should not be able to know about. I also think we should probably add the getSnapshottableDirListing API to the HdfsAdmin class, so that users writing programs against HDFS that use/list snapshots will have a public API they can use. > Listing all the current snapshottable directories > ------------------------------------------------- > > Key: HDFS-4230 > URL: https://issues.apache.org/jira/browse/HDFS-4230 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: datanode, namenode > Reporter: Jing Zhao > Assignee: Jing Zhao > Attachments: HDFS-4230.001.patch, HDFS-4230.001.patch, > HDFS-4230.002.patch, HDFS-4230.003.patch > > > Provide functionality to provide user with metadata about all the > snapshottable directories. -- This message is automatically generated by JIRA.
