-----------------------------------
Summary: LiteralExpr incorrectly "handles" DATE, DATETIME, and
TIMESTAMP
Key: IMPALA-7897
URL: https://issues.apache.org/jira/browse/IMPALA-7897
Project: IMPALA
Issue Type: Bug
Components: Frontend
Affects Versions: Impala 3.0
Reporter: Paul Rogers
Assignee: Paul Rogers
The {{LiteralExpr.create()}} method “handles” the {{DATE}}, {{DATETIME}}, and
{{TIMESTAMP}} class by returning a null value, with no exception. Change this
to throw an exception so that calling code does not have to track down an NPE.
That is, if literals of these types are not supported, then make this clear by
throwing an {{UnsupportedOperationException}} or the like.
