-----------------------------------
Assignee: (was: Paul Rogers)
> LiteralExpr fails with class cast expression for some invalid DECIMAL values
> ----------------------------------------------------------------------------
>
> Key: IMPALA-7898
> URL: https://issues.apache.org/jira/browse/IMPALA-7898
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Affects Versions: Impala 3.0
> Reporter: Paul Rogers
> Priority: Minor
>
> Suppose that we run this simple test:
> {code:java}
> LiteralExpr.create("123.1", ScalarType.createDecimalType(4, 2));
> {code}
> This method calls {{NumericLiteral.uncheckedCastTo()}} which will return a
> {{CastExpr}}. The code then casts this to a {{LiteralExpr}}, which will fail
> with a runtime {{ClassCastException}}.
> We should provide a clearer error message such as explaining that the value
> is invalid for the given type rather than just throwing a seemingly-unrelated
> exception.
