>
> 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.
