-----------------------------------

    Attachment: HIVE-6572.patch

Patch attached.

[~owen.omalley], could you please check this patch real quick?

[~rhbutani], I would like this patch to also be included in the hive-0.13 release, since it fixes some erroneous config usage introduced in the 0.13 timeframe, and we don't want to have a release with them, which might make this behaviour something we have to support in the longer run.

> HadoopShims has a method to fetch config parameters by name so that they return the appropriate config param name for the appropriate hadoop version. We need to be consistent about using these versions.
> For eg:. mapred.min.split.size is deprecated with hadoop 2.x, and is instead called mapreduce.input.fileinputformat.split.minsize .
> Also, there is a bug in Hadoop20SShims and Hadoop20Shims that defines MAPREDMINSPLITSIZEPERNODE as mapred.min.split.size.per.rack and MAPREDMINSPLITSIZEPERRACK as mapred.min.split.size.per.node. This is wrong and confusing.
