数据源字段变化引发异常

大家好，最近在设计完model和cube后，需要对数据源表进行修改，比如增加字段或者修改字段，但是在reload table 时出现了问题，提示需要对cube进行 purge操作。但是disable 和purge后，问题依旧存在。

Kylin 版本：2.6.1

Hi Shen june:

If you change the field name of the data source, you need to delete the model and cube used in the field to reload the table, otherwise there will be a conflict. In general, after designing the model and cube, we do not recommend any changes to the table structure, especially the fields that have been used.
