Chris Nauroth commented on MAPREDUCE-5886:

Hi, [~jira.shegalov] and [~ajisakaa]. Thanks for looking at this and
contributing some new ideas.
Regarding {{FileInputFormat#addInputPaths}}, in addition to the issue raised by
Akira for supporting comma in a file name, there is another reason why I didn't
use that method. On Windows Command Prompt, the comma acts as an argument
separator, much like space. This would have the potential to create confusion
for users on Windows.
The basic concept of the new API looks good to me. We might instead consider
passing varargs and no range indices. Word count could chop the input args
down to the correct range using {{Arrays#copyOfRange}} or {{List#subList}}.
Would you mind moving all of the API work to another jira? MAPREDUCE-5889
probably would work for that. For this issue, I was hoping to put in a quick
trivial patch in just word count to enable this. IOW, I'd like to pursue a
binding +1 on patch v1 and commit it.
Thanks again!

bq. I considered both {{Arrays#copyOfRange}} and {{List#subList}} but discarded
this due to creation of throwaway objects.
It's not too bad for {{ArrayList#subList}}. It retains the original array and
wraps it with different offset indices:
http://hg.openjdk.java.net/jdk6/jdk6/jdk/file/tip/src/share/classes/java/util/ArrayList.java#l891
You pay a flat cost for the extra indices and object overhead, but it's not a
full array reallocation.

LGTM. Possibly we can add a method to FIF:

/**

public static addInputPaths(Job job, String[] args, int offset, int numArgs);

Then it can be used in other jobs and reused in FIF for
