寫入數據到hive的hdfs文件中即可，hive創建表的時候用小寫做表名，不然查不到
相關操作如下：
查看目錄與表
hive> dfs -ls /user/hive/warehouse/
准備hive腳本文件與測試數據文件
[root@master hive]# cat /opt/flight.hive create table flight ( last_name string, first_name string, arrival_time string, meeting_location string, info_comment string) ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t';
[root@master hive]# cat tmp_data/flight_data.txt BUCKLEY SUMMER 10/12/2010 14:48 10/12/2010 14:45 WH CLOONEY GEORGE 10/12/2010 14:47 10/12/2010 14:45 WH PRENDERGAST JOHN 10/12/2010 14:48 10/12/2010 14:45 WH LANIER JAZMIN 10/12/2010 14:48 10/12/2010 14:45 WH BILL SIGNING/ MAYNARD ELIZABETH 10/13/2010 12:34 10/13/2010 13:00 WH BILL SIGNING/ 數據文件說明：字段之間使用'\t'隔開
創建表格
[root@master hive]# hive -f /opt/flight.hive 此時沒有表中沒有數據
hive> select * from flight; OK Time taken: 1.464 seconds 復制數據文件到warehouse目錄下面,查看數據
[root@master hive]# hadoop fs -put ./tmp_data/visits_data.txt /user/hive/warehouse/flight/ hive> select * from flight; OK BUCKLEY SUMMER 10/12/2010 14:48 10/12/2010 14:45 WH NULL NULL CLOONEY GEORGE 10/12/2010 14:47 10/12/2010 14:45 WH NULL PRENDERGAST JOHN 10/12/2010 14:48 10/12/2010 14:45 WH NULL LANIER JAZMIN 10/12/2010 14:48 10/12/2010 14:45 WH BILL SIGNING/ MAYNARD ELIZABETH 10/13/2010 12:34 10/13/2010 13:00 WH BILL SIGNING/ Time taken: 2.561 seconds, Fetched: 5 row(s) 刪除表格后再觀察數據文件
hive> drop table flight;
OK
Time taken: 0.024 seconds hive> dfs -ls /user/hive/warehouse/flight; ls: `/user/hive/warehouse/people_visits': No such file or directory
