Todd Lipcon resolved HDFS-1412.
-------------------------------
Resolution: Duplicate
Dup of HADOOP-6378
> Broken symlinks break the local filesystem implementation of HDFS on linux
> --------------------------------------------------------------------------
>
> Key: HDFS-1412
> URL: https://issues.apache.org/jira/browse/HDFS-1412
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 0.20.2
> Environment: Ubuntu 9.10 Lucid
> Reporter: Ed Kohlwey
>
> When calling listStatus() on a directory containing broken symlinks, a
> FileNotFound exception is thrown.
> The problem is that even though File.list() returns an entry for the symlink,
> calling File.exists() on a file with that path will return false.
> I would suggest either checking that files exist in
> RawLocalFileSystem.listStatus() before calling getFileStatus(), and if a file
> doesn't exist don't put in in the result (less work), or modify the
> RawLocalFileSystem implementation to treat broken symlinks as files of length
> 0 (more work), or add an exists() method to FileStatus (perhaps even more
> work, and involves changing the API).
> Here's the relevant section of the stack trace.
> java.io.FileNotFoundException: File XXX does not exist.
