写入数据到hive的hdfs文件中即可，hive创建表的时候用小写做表名，不然查不到
相关操作如下：
查看目录与表
hive> dfs -ls /user/hive/warehouse/
准备hive脚本文件与测试数据文件
[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/ 数据文件说明：字段之间使用'\t'隔开
创建表格
[root@master hive]# hive -f /opt/flight.hive 此时没有表中没有数据
hive> select * from flight; OK Time taken: 1.464 seconds 复制数据文件到warehouse目录下面,查看数据
[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) 删除表格后再观察数据文件
hive> drop table flight;
OK
