James Taylor updated PHOENIX-1827:
----------------------------------
Issue Type: Bug (was: Task)
> TrackOrderPreservingExpressionCompiler may falsely say ORDER BY is order
> preserving
> -----------------------------------------------------------------------------------
>
> Key: PHOENIX-1827
> URL: https://issues.apache.org/jira/browse/PHOENIX-1827
> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor
> Assignee: James Taylor
> Fix For: 4.5.0
>
>
> TrackOrderPreservingExpressionCompiler defaults to order preserving and sets
> to false when certain constructs are encountered. This is problematic because
> new types of expressions may be added to ExpressionCompiler that are not
> order preserving. There are already cases like this which need to be fixed,
> but better would be to restructure TrackOrderPreservingExpressionCompiler as
> an Expression visitor instead (PHOENIX-1826).
