Major Description
Now in webhcat, when using GET ddl/database/:db/table/:table and "format=extended", return value is based on query "show table extended like". However, this query doesn't contains serde info like "line.delim" and "filed.delim". In this case, user won't have enough information to reconstruct the exact same table based on the information from the json file. The "descExtendedTable" function in HcatDelegator should also return extra fields from query "desc extended tablename" which contains fields "sd", "retention", "parameters" "parametersSize" and "tableType".
