> 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
