[jira] Updated: (HADOOP-6229) Atempt to make a directory under an existing file on LocalFileSystem should throw an Exception.

["Boris Shkolnik (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-6229?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Boris Shkolnik updated HADOOP-6229:
-----------------------------------

    Attachment: HADOOP-6229.patch

Took Nikolas' suggestion. Created new class FileAlreadyExestsException.
Turns out mapred already has such class. 
After this patch is committed I will remove mapred's one and make it use this one (from common).
Also I will need to change HDFS to use this new exception instead of FileNotFound.

> Actually HDFS throws FileNotFoundException in this case (in FSDirectory.mkdirs() ). So I guess we should do the same.
