hive的数据表分为两种，内部表和外部表。内部表指hive创建并通过load data inpath进数据库的表，这种表可以理解为数据和表结构都

CREATE EXTERNAL TABLE IF NOT EXISTS database.table1
(
column1 STRING COMMENT 'comment1',
column2 STRING COMMENT 'comment2'
)
ROW FORMAT DELIMITED FIELDS TERMINATED BY "\t"
STORED AS INPUTFORMAT "com.hadoop.mapred.DeprecatedLzoTextInputFormat" OUTPUTFORMAT "org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat"
LOCATION 'hdfs:///data/dw/asf/20120201';

标红部分是十分操蛋的，网上几乎所有涉及该单词的文章基本全是复制粘贴抄的，，无一例外，全部写成SORTED，如果你找的hive中文资料不是我这篇，恐怕创建外部表都会报错。
