> Key: HIVE-872
> URL: https://issues.apache.org/jira/browse/HIVE-872
> Project: Hive
> Issue Type: New Feature
> Reporter: Zheng Shao
> Assignee: Syed S. Albiz
> Fix For: 0.8.0
>
> Attachments: HIVE-872.1.patch, HIVE-872.6.patch, HIVE-872.7.patch
>
>
> Original request: We should allow "0L" to be interpreted as a bigint constant.
> Instead of this, we have decided that the usecases for this do not merit
> modifications to the ql. Instead we enable type widening on the UDF COALESCE
> and on the UNION ALL operator
