Subject [jira] Created: (HDFS-1088) Prevent renaming a symlink to it's target
Date Thu, 08 Apr 2010 02:11:43 GMT
Prevent renaming a symlink to it's target 

                 Key: HDFS-1088
                 URL: https://issues.apache.org/jira/browse/HDFS-1088
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
            Reporter: Eli Collins
            Assignee: Eli Collins

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
