[jira] [Commented] (SPARK-26218) Throw exception on overflow for integers

    [ https://issues.apache.org/jira/browse/SPARK-26218?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16814709#comment-16814709 ] 

Reynold Xin commented on SPARK-26218:
-------------------------------------

> SPARK-24598 just updated the documentation in order to state that our addition is a Java style one and not a SQL style. But in order to follow the SQL standard we should instead throw an exception if an overflow occurs.
