Chris Nauroth updated HADOOP-10178:
-----------------------------------

    Target Version/s: 3.0.0, 2.3.0
        Hadoop Flags: Reviewed

Good catches Shanyu, and thank you for posting the summary of the behavior.  
I'm +1 for the v7 patch.

[~tucu00], I'm planning to commit later today unless you object.  Shanyu's 
comment about the source message makes sense to me, but maybe we can change it 
later in a separate patch if you have something else in mind.  Thanks for 
helping to review this patch.

> Even if you use any new configuration properties, you still find "deprecated" 
> warnings in your logs. E.g.:
> 13/12/14 01:00:51 INFO Configuration.deprecation: mapred.input.dir.recursive 
> is deprecated. Instead, use 
> mapreduce.input.fileinputformat.input.dir.recursive
