Yuanbo Liu updated HDFS-10756: ------------------------------ Release Note: "getTrashRoot" returns a trash root for a path. Currently in DFS if the path "/foo" is a normal path, it returns "/user/$USER/.Trash" for "/foo" and if "/foo" is an encrypted zone, it returns "/foo/.Trash/$USER" for the child file/dir of "/foo". This patch is about to override the old "getTrashRoot" of httpfs and webhdfs, so that the behavior of returning trash root in httpfs and webhdfs are consistent with DFS. (was: "getTrashRoot" returns a trash root for a path. Currently in DFS if the path "/foo" is a normal path, it returns "/user/$USER/.Trash" for "/foo" and if "/foo" is an encrypted zone, it returns "/foo/.Trash/$USER" for the child file/dir of "/foo".

Default trash dir is under > {{/user/$USER}} > For an encrypted file, since moving files between/in/out of EZs are not > allowed, when an EZ file is deleted via CLI, it calls in to [DFS > implementation|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/DistributedFileSystem.java#L2485] > to move the file to a trash directory under the same EZ. > This works perfectly fine for CLI users or java users who call FileSystem > API. But for users via httpfs/webhdfs, currently there is no way to figure > out what the trash root would be. This jira is proposing we add such > interface to httpfs and webhdfs. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
