> Internally, Hive {{ShimLoader}} tries to load different versions of Hadoop shims by checking version information gathered from Hadoop jar files.  If the major version number is 1, {{Hadoop20SShims}} will be loaded.  Otherwise, if the major version number is 2, {{Hadoop23Shims}} will be chosen.  However, CDH Hadoop versions like 2.0.0-mr1-cdh4.1.1 have 2 as major version number, but contain Hadoop 1 code.  This confuses Hive {{ShimLoader}} and loads wrong version of shims.
