我试图加载在cassandra sing cql命令中创建的简单表。但当我尝试转储时加载失败。我的pig脚本如下所示。
A = LOAD 'cql://pigtest/myusers' USING CqlStorage()
AS (user_id:int,fname:chararray,lname:chararray);
describe A;
DUMP A;
我的用户表架构看起来像
CREATE TABLE users (
user_id int ( primary key),
fnam text,
lname text
)
我遇到了以下异常(我尝试了cassandra2.0.9和2.1.0,以及pig0.13)。请帮助我们找到根本原因/
ERROR 1002: Unable to store alias A
Caused by: InvalidRequestException(why:Expected 8 or 0 byte long (7))
