 出现

关键在于sqoop在计算split-by切片字段时：OriginalSql = SELECT MIN(YEAR), MAX(YEAR) FROM (SELECT
    TO_NUMBER(TO_CHAR(GCRQ, 'YYYY')) AS gcrq_year,
    TO_NUMBER(TO_CHAR(GCRQ, 'MM')) AS gcrq_month,
    TO_NUMBER(TO_CHAR(GCRQ, 'DD')) AS gcrq_day,
    .......
FROM LZJHGX.DAT_DCSJ_TIME
WHERE TO_CHAR(GCRQ , 'YYYY-MM-DD') = TO_CHAR(SYSDATE, 'YYYY-MM-DD') AND  (1 = 1) ) AS t1,

使用 AS t1的语法，Oracle是不支持select * from (select * from A) as t1，这种子查询AS 命名表名的写法。

那么sqoop脚本中如何避免呢？

解决办法：删除掉driver参数--driver oracle.jdbc.driver.OracleDriver
