             Summary: Fix NullPointerException in getLinkTarget
                 Key: HADOOP-9415
                 URL: https://issues.apache.org/jira/browse/HADOOP-9415
             Project: Hadoop Common
          Issue Type: Sub-task
    Affects Versions: 3.0.0
            Reporter: Andrew Wang
            Priority: Minor


{{HdfsFileStatus#getLinkTarget}} can throw a NPE in {{DFSUtil#bytes2String}} if 
{{symlink}} is null. Better to instead return null and propagate this to the 
client.
