> Change the precison/scale for intermediate sum result in the avg() udf
> -----------------------------------------------------------------------
>
> Key: HIVE-6459
> URL: https://issues.apache.org/jira/browse/HIVE-6459
> Project: Hive
> Issue Type: Improvement
> Components: UDF
> Affects Versions: 0.13.0
> Reporter: Xuefu Zhang
> Assignee: Xuefu Zhang
> Attachments: HIVE-6459.1.patch, HIVE-6459.patch
>
>
> The avg() udf, when applied to a decimal column, selects the precision/scale
> of the intermediate sum field as (p+4, s+4), which is the same for the
> precision/scale of the avg() result. However, the additional scale increase
> is unnecessary, and the problem of data overflow may occur. The requested
> change is that for the intermediate sum result, the precsion/scale is set to
> (p+10, s), which is consistent to sum() udf. The avg() result still keeps its
> precision/scale.
