Answer 1

这里加载非ORC文件，这就是发生此错误的原因。因此，最佳解决方案是首先使表加载数据并将此表插入orc表

CREATE TABLE data(value1 string, value2 string)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '|';

终止于b＆＃34; |＆＃34;因为我正在使用PSV文件，您可以根据您的文件格式设置。

LOAD DATA INPATH '/user/hive/data.psv' INTO TABLE data;

create data2 stored as ORC tblproperties ("orc.compress" = "SNAPPY");

insert into data2 select * from data;

Answer 2

您需要确保您的HIVE版本大于0.11。 ORC是在0.11版本中引入的

ORC         -- (Note: Available in Hive 0.11.0 and later)

如何查看hive版本

$ hive --version
Hive 0.14.0.2.2.4.8-40

HIVE-3874: Create a new Optimized Row Columnar file format for Hive. - 这是执行票。
Hive Create Table syntax - 检查file_format以了解每种存储类型的最低要求。
