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

             Summary: Use shimmed version of hadoop conf names for 
mapred.{min,max}.split.size{.*}
                 Key: HIVE-6572
                 URL: https://issues.apache.org/jira/browse/HIVE-6572
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.13.0, 0.14.0
            Reporter: Sushanth Sowmyan
            Assignee: Sushanth Sowmyan


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.
