spark中报错：com.fasterxml.jackson.databind.JsonMappingException: Incompatible Jackson version: 2.9.10-1

spark中报错：

com.fasterxml.jackson.databind.JsonMappingException: Incompatible Jackson version: 2.9.10-1

JsonMappingException不兼容的Jackson版本：2.9.10-1

出现这个错误是版本不兼容，可能你之前下了高版本或者低版本的jackson，我报这个错应该是找到这个包删了再下的但是找起来太麻烦了，所以就重新在idea上创建了一个新项目，导入了pom.xml文件
