      Description

      I created a symlink using

      ...
          FileContext fc = FileContext.getFileContext(dst.fs.getUri());
          for (PathData src : srcs) {
            fc.createSymlink(src.path, dst.path, false);
          }
      

      After doing this to create a symlink /foo/too.txt -> /foo/hello.txt, I tried to hdfs fsck and got the following:

      [adi@host01 ~]$ hdfs fsck /
      Connecting to namenode via http://host01:21070
      FSCK started by adi (auth:SIMPLE) from /172.29.122.91 for path / at Fri Nov 16 15:59:18 PST 2012
      FSCK ended at Fri Nov 16 15:59:18 PST 2012 in 3 milliseconds
      hdfs://host01:21020/foo/hello.txt
      
      
      Fsck on path '/' FAILED
      

      It's very surprising that an unprivileged user can run code which so easily causes a fundamental administration tool to fail.
