----------------------------------
Summary: when we move symlink to symlink ,rename will move the
real dir to symlink
Key: HDFS-12330
URL: https://issues.apache.org/jira/browse/HDFS-12330
Project: Hadoop HDFS
Issue Type: Bug
Components: symlinks
Reporter: Mingchen_Ma
In function DistributedFileSystem/rename, when dfs.rename is done for the
first time, the path 'absSrc' will be replaced with real pathway if
UnresolvedLinkException is caught. Then if the operation is symlink to symlink,
the real dir pointed at by symlink will move to targeted dir. And the source of
symlink will remain in an invalid state. Actually I think when
UnresolvedLinkException first happens, we should firstly replace targeted dir
and deal with the source dir of UnresolvedLinkException in
FileSystemLinkResolver, because in reality, no UnresolvedLinkException will
happen if we rename on symlink to real dir,so that we can move the symlink as
we expected.
