运行通过maven构建好的jar出错：  
Exception in thread “main” org.apache.spark.sql.catalyst.analysis.NoSuchTableException: Table or view ‘zgw’ not found in database ‘default’;

根据异常信息提示的很明显，就是说找不到这个表在default这个数据库中，我去hive中查询了一下,  
![keyi][]  
可以看到是存在这个hive表的。  
解决方法：  
**将hive的hive-site.xml拷贝到放入$SPARK-HOME/conf目录下即可。**
