<description>The default input format, if it is not specified, the system
assigns it. It is set to HiveInputFormat for hadoop versions 17, 18 and 19,
whereas it is set to CombineHiveInputFormat for hadoop 20. The user can always
overwrite it - if there is a bug in CombineHiveInputFormat, it can always be
manually set to HiveInputFormat. </description>
