hive - TBLPROPERTIES('skip.header.line.count'='1') 不适用于从直线连接到 hive jdbc 1.2.1 的 sparkThrift

Question

我正在使用 spark 2.3 并将 sparkThrift 与直线连接。

Hive jdbc 版本 1.2.1 Spark SQL 版本 2.3.1

我正在尝试使用跳过标头属性创建外部表，但选择命令始终返回带有标头的数据作为第一行，下面是我的创建查询

CREATE EXTERNAL TABLE datasourcename11(
`retail_invoice_detail_sys_invoice_no` STRING,
`store_id` STRING,
`retail_invoice_detail_invoice_time` STRING,
`retail_invoice_detail_invoice_date` string,
`cust_id` STRING,
`article_code` INTEGER,
`retail_invoice_detail_base_price` INTEGER,
`retail_invoice_detail_sale_price` INTEGER,
`retail_invoice_detail_quantity` DOUBLE,
`retail_invoice_detail_total_amount` DOUBLE
) 
ROW FORMAT DELIMITED  FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n'  
LOCATION '/home/java_services/backend/demo/' 
TBLPROPERTIES('skip.header.line.count'=1);

Answer 1

此属性skip.header.line.count=1仅在 Hive 中受支持。

解决方法是使用过滤器

retail_invoice_detail_sys_invoice_no!=<col name in header>
