Yin Huai updated SPARK-16642:
-----------------------------
    Target Version/s: 2.0.1  (was: 2.0.0)

> ResolveWindowFrame should not be triggered on UnresolvedFunctions.
> ------------------------------------------------------------------

>                 Key: SPARK-16642
>                 URL: https://issues.apache.org/jira/browse/SPARK-16642
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>            Reporter: Yin Huai

> The case at https://github.com/apache/spark/blob/75146be6ba5e9f559f5f15430310bb476ee0812c/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L1790-L1792 is shown below
> {code}
> case we @ WindowExpression(e, s @ WindowSpecDefinition(_, o, UnspecifiedFrame)) =>
>           val frame = SpecifiedWindowFrame.defaultWindowFrame(o.nonEmpty, acceptWindowFrame = true)
>           we.copy(windowSpec = s.copy(frameSpecification = frame))
> {code}
> This case will be triggered even when the function is an unresolved. So, when the functions like lead are used, we may see errors like {{Window Frame RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW must match the required frame ROWS BETWEEN 1 FOLLOWING AND 1 FOLLOWING.}} because we wrongly set the the frame specification.
