Question

我的主要需求是使用INSERT OVERWRITE uery从HIVE加载HDFS文件。在这个查询中，我试图加入3个hive表。以下是查询：

select * FROM 
    AGG_CUSTOMER_EXPSR_DRV_HIVE DRV 
LEFT OUTER JOIN 
    AGG_CUSTOMER_EXPSR_SRC_HIVE SRC 
ON 
    (SRC.CUSTOMER_ID = DRV.CUSTOMER_ID) 
    AND (SRC.AGGREGATION_LEVEL_CD = DRV.AGGREGATION_LEVEL_CD) 
    AND (SRC.PRODUCT_GROUP_CD = DRV.PRODUCT_GROUP_CD) AND (SRC.SRC_SYS_CD = DRV.SRC_SYS_CD) 
LEFT OUTER JOIN 
    ALTERNATE_IP_HIVE AIP1 
ON 
    (DRV.DERIVED_CUSTOMER_ID = AIP1.IP_ID) AND (AIP1.IP_TYPE_CD IN (1, 4)) 
LEFT OUTER JOIN 
    ALTERNATE_IP_HIVE AIP3 
ON 
    (SRC.FINANCIAL_RPTNG_UNIT_ID = AIP3.IP_ID) AND (AIP3.IP_TYPE_CD = 3) 
WHERE EXCLUDE_IND ='N';

但我收到的错误如下： -sh: syntax error near unexpected token（`

有人可以帮我找出问题吗？

注意：我删除了SELECT子句中的字段。

如果您在hive中创建了一个表，其中包含上述sql中的结果字段数，那么您可以简单地执行

INSERT OVERWRITE TABLE <database_name.your_created_table_name> SELECT * FROM 
    AGG_CUSTOMER_EXPSR_DRV_HIVE DRV 
LEFT OUTER JOIN 
    AGG_CUSTOMER_EXPSR_SRC_HIVE SRC 
ON 
    (SRC.CUSTOMER_ID = DRV.CUSTOMER_ID) 
    AND (SRC.AGGREGATION_LEVEL_CD = DRV.AGGREGATION_LEVEL_CD) 
    AND (SRC.PRODUCT_GROUP_CD = DRV.PRODUCT_GROUP_CD) AND (SRC.SRC_SYS_CD = DRV.SRC_SYS_CD) 
LEFT OUTER JOIN 
    ALTERNATE_IP_HIVE AIP1 
ON 
    (DRV.DERIVED_CUSTOMER_ID = AIP1.IP_ID) AND (AIP1.IP_TYPE_CD IN (1, 4)) 
LEFT OUTER JOIN 
    ALTERNATE_IP_HIVE AIP3 
ON 
    (SRC.FINANCIAL_RPTNG_UNIT_ID = AIP3.IP_ID) AND (AIP3.IP_TYPE_CD = 3) 
WHERE EXCLUDE_IND ='N';

来自SELECT的

它是您的查询。您可以查看this URL以获取有关hiveql的更多帮助

使用INSERT OVERWRITE DIRECTORY无法从HIVE表插入HDFS
