   <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>
