Suresh Srinivas commented on HDFS-1088:
---------------------------------------
I am not able to check the test report to see which test failed. Eli, can you
please comment on the failed test and if it is unrelated to this patch, when
you can access hudson? I will commit the patch after that.
> Prevent renaming a symlink to its target

> 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
