      Description

      Here's the HDFS side of HADOOP-6563:

      • Small bug fix for renaming a symlink to it's target
      • Hdfs#getFileBlockLocations needs to use getUriPath() to ensure an absolute path is passed in. See minor change to INode#getPathNames, which now asserts instead of returning null and causing NPEs. This was exposed via calling FileContext#getFileBlockLocations using a symlink.
      • Comment in FSImage around symlinks and image loading
