Andrew Wang created HADOOP-9761: ----------------------------------- Summary: ViewFileSystem#rename fails when using DistributedFileSystem Key: HADOOP-9761 URL: https://issues.apache.org/jira/browse/HADOOP-9761 Project: Hadoop Common Issue Type: Bug Components: viewfs Affects Versions: 3.0.0, 2.1.0-beta Reporter: Andrew Wang Assignee: Andrew Wang
ViewFileSystem currently passes unqualified paths (no scheme or authority) to underlying FileSystems when doing a rename. DistributedFileSystem symlink support added in HADOOP-9418 needs to qualify and check rename sources and destinations since cross-filesystem renames aren't supported, so this breaks in the following way - Default FS URI is configured to viewfs://<viewfs> - When doing a rename, ViewFileSystem checks to make sure both src and dst FileSystems are the same (which they are, both in same DFS), and then calls DistributedFileSystem#rename with unqualified "remainder" paths - Since these paths are unqualified, DFS qualifies them with the default FS to check that it can do the rename. This turns it into viewfs://<viewfs>/<path> - Since viewfs://<viewfs> is not the DFS's URI, DFS errors out the rename. -- This message is automatically generated by JIRA.
