Bingz2 opened a new pull request, #2085:
URL: https://github.com/apache/incubator-seatunnel/pull/2085

   https://github.com/apache/incubator-seatunnel/issues/2084
   
   从hive中读到的数据跟列名一样，而不是真实的数据

   如果查询的字段类型时数字的话，就会爆出以下异常

   通过查看Spark源码，发现在通过Jdbc读数据在拼接列名时使用的是双引号加加列名，所以才会导致一直没有返回正确的数据

   解决方法就是重新实现hive的dialect
