将CSV数据加载到Hive表时出错

Question

我有一个CSV文件,其中包含以下格式的行,

1, 11812, 15273, "2016-05-22T111647.800 US/Eastern", 82971850, 0
1, 11812, 7445, "2016-05-22T113640.200 US/Eastern", 82971928, 0
1, 11654, 322, "2016-05-22T113845.773 US/Eastern", 82971934, 0
1, 11722, 0, "2016-05-22T113929.541 US/Eastern", 82971940, 0

我使用以下命令创建一个Hive表,

create table event_history(status tinyint, condition smallint,
machine_id int, time timestamp, ident int, state tinyint)

然后我尝试使用以下命令将CSV文件加载到表中,

load data local inpath "/home/ubuntu/events.csv" into table event_history;

但是当我尝试在创建的表中执行select查询时,我得到的只是NULL.我在这里错过了什么？

Hive版本是Hive 1.2.1

我的错误是在表创建中.通过以下更改修复了它

create table event_history(status tinyint, condition smallint, machine_id int,
time timestamp, drqs int, state tinyint) ROW FORMAT DELIMITED FIELDS TERMINATED BY ',';
