------------------------------------------------

                 Key: HADOOP-7342
                 URL: https://issues.apache.org/jira/browse/HADOOP-7342
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 0.23.0
            Reporter: Bharath Mundlapudi
            Assignee: Bharath Mundlapudi
            Priority: Minor
             Fix For: 0.23.0


Java File.list API can return null when disk is bad or directory is not a 
directory. This utility API in FileUtil will throw an exception when this 
happens rather than returning null.
