------------------------------------
Summary: The query option for decimal_v2 should be false by default
Key: IMPALA-13559
URL: https://issues.apache.org/jira/browse/IMPALA-13559
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Reporter: Maxwell Guo
Assignee: Maxwell Guo
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.
