> SARGs: Type Safety via PredicateLeaf.type
> -----------------------------------------

> Key: HIVE-10286
> URL: https://issues.apache.org/jira/browse/HIVE-10286
> Project: Hive
> Issue Type: Bug
> Components: File Formats, Serializers/Deserializers
> Reporter: Gopal V
> Assignee: Prasanth Jayachandran
> Attachments: HIVE-10286.1.patch, HIVE-10286.2.patch

>
> The Sargs impl today converts the statsObj to the type of the predicate
> object before doing any comparisons.
> To satisfy the PPD requirements, the conversion has to be coerced to the type
> specified in PredicateLeaf.type.
> The type conversions in Hive are standard and have a fixed promotion order.
> Therefore the PredicateLeaf has to do type changes which match the exact
> order of type coercions offered by the FilterOperator.
