Chuan Liu commented on HADOOP-9043: ----------------------------------- I am +1 on the existing patches to fix the unusable symlinks. Should we open a new JIRA to investigate readlink problem? On the readlink implementation I agree with the general approach Chris has described. Some logic is already implemented in libwinutils as Ivan mentioned. I also think GetFinalPathNameByHandle() may be easier to use than the DeviceIoControl(). > winutils can create unusable symlinks > ------------------------------------- > > Key: HADOOP-9043 > URL: https://issues.apache.org/jira/browse/HADOOP-9043 > Project: Hadoop Common > Issue Type: Bug > Components: util > Affects Versions: 3.0.0, 1-win > Reporter: Chris Nauroth > Assignee: Arpit Agarwal > Fix For: 3.0.0, 1-win > > Attachments: HADOOP-9043.branch-1.2.patch, > HADOOP-9043.branch-1-win.patch, HADOOP-9043.trunk.2.patch, > HADOOP-9043.trunk.3.patch, HADOOP-9043.trunk.patch > > > In general, the winutils symlink command rejects attempts to create symlinks > targeting a destination file that does not exist.
