> Key: IMPALA-13559
> URL: https://issues.apache.org/jira/browse/IMPALA-13559
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Reporter: Maxwell Guo
> Assignee: Maxwell Guo
> Priority: Major
>
> 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.
