> The [decimal_v2 query option|https://github.com/apache/impala/blob/master/common/thrift/Query.thrift#L304] is true by default, for user that using impala3 the will meet  the exception for Incompatible  AnalysisException,and user can fix the problem by  SET DECIMAL_V2=FALSE.
> So for me I think it is better to set decimal_v2 to false in order to forward compatible, and should also be the principle of software development.
