insert overwrite local directory '/export/servers/exporthive/a'
select * from score;
insert overwrite local directory '/export/servers/exporthive' row format delimited fields terminated by '\t' collection items terminated by '#'
select * from student;
collection items terminated by '#' 對集合型別使用#來進行分割
insert overwrite directory '/export/servers/exporthive' row format delimited fields terminated by '\t' collection items terminated by '#'
select * from score;
注: 對於集合型別我們使用#來進行分割，因為這個表裡面沒有集合型別，所以加不加這個結果都一樣
