Ok so the behavior is a little different when using
FileInputFormat.addInputPath
as opposed to using pig. Ill try the glob.
Thanks

I believe that opening a directory as a file will result in a file not found.
You probably need to set it to a glob, that points to that actual files.
Something like
/user/root/logs/2011/*/*/* for all entries in 2011, or
/user/root/logs/2011/01/*/* if you want to restrict it to just January. By
default if you pass in a directory as input the input format will assume that
the directory contains only files, no sub directories and that you really want
to use each of those files an input.

How can I tell my job to include all the subdirectories and their
content of a certain path?
My directory structure is as follows: logs/{YEAR}/{MONTH}/{DAY} and I
tried setting my input path to 'logs/' using
FileInputFormat.addInputPath however I keep receiving the following error:
ava.io.FileNotFoundException: File does not exist: /user/root/logs/2011/01

Do my directories/directory contents need to be in any particular format?
Thanks
