本文介绍了TBLPROPERTIES('skip.header.line.count'='1') 不适用于从直线与 hive jdbc 1.2.1 连接的 sparkThrift的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用 spark 2.3 并将 sparkThrift 与直线连接.
I am using spark 2.3 and connecting sparkThrift with beeline.
Hive jdbc 版本 1.2.1Spark SQL 2.3.1 版
Hive jdbc version 1.2.1Spark SQL version 2.3.1
我正在尝试使用跳过标题属性创建外部表，但选择命令总是返回标题为第一行的数据，下面是我的创建查询
I am trying to create external table with skip header property but select command is always returning data with header as first row, below is my create query
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);
推荐答案
此属性 skip.header.line.count=1 仅在 Hive 中受支持.
This property skip.header.line.count=1 is supported in Hive only.
解决方法是使用过滤器
retail_invoice_detail_sys_invoice_no!=
