> Lot of show ... specific codes are under the
> org.apache.hadoop.hive.ql.metadata.formatting package which are used only by
> these commands. Also the two MetaDataFormatters (JsonMetaDataFormatter,
> TextMetaDataFormatter) are trying to do everything, while they contain a lot
> of code duplications. Their functionalities should be put under the
> directories of the appropriate show commands.
