导入报错，报错提示如下

解决方法
导入的时候不导入comment。使用如下命令即可导入成功
impdp system/Cloud#osshk directory=data_pump_dir dumpfile=20180712.dmp logfile=20180712.log schemas=xx,ss EXCLUDE=comment
解决思路
导入的时候报错了，一般就是看在导入什么东西的时候报的错，报错信息的第5行提示是在
Processing object type SCHEMA_EXPORT/TABLE/COMMENT
那么我在导入的时候直接排除comment就好了，comment在导入完成后想其他办法重新生成吧。
