Description

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.
