[jira] Updated: (HADOOP-278) a missing map/reduce input directory does not produce a user-visible error message

     [ http://issues.apache.org/jira/browse/HADOOP-278?page=all ]

Owen O'Malley updated HADOOP-278:
---------------------------------

    Attachment: input-dir-check.patch

This patch adds a method for InputFormat that checks to see if a list of input paths is valid. InputFormatBase implements the simple check to make sure that each path represents a directory. JobClient checks the validity of each path and stops the job submission with a message to the user if any directories are invalid.
