> Hive Union Type Mismatch
> ------------------------
>
> Key: HIVE-11919
> URL: https://issues.apache.org/jira/browse/HIVE-11919
> Project: Hive
> Issue Type: Bug
> Reporter: Laljo John Pullokkaran
> Assignee: Laljo John Pullokkaran
> Attachments: HIVE-11919.1.patch, HIVE-11919.2.patch
>
>
> In Hive for union right most type wins out for most primitive types during
> plan gen. However when union op gets initialized the type gets switched.
> This could result in bad data & type exceptions.
> This happens only in non cbo mode.
> In CBO mode, Hive would add explicit type casts that would prevent such type
> issues.
> Sample Query:
> select cd/sum(cd) over() from(select cd from u1 union all select cd from u2
> union all select cd from u3)u4;
