I suppose, I don't understand why I'm limited to 1 preceding.
> Error message is not very clear

> Key: SPARK-17466
> URL: https://issues.apache.org/jira/browse/SPARK-17466
> Project: Spark
> Issue Type: Improvement
> Reporter: Tim Chan
> Priority: Trivial
>
> User class threw exception: org.apache.spark.sql.AnalysisException: Window
> Frame RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW must match the
> required frame ROWS BETWEEN 1 PRECEDING AND 1 PRECEDING;
> The same Spark SQL that throws this exception in EMR 5.0.0 works just fine in
> Databricks using Spark 2.0.0/Scala 2.11. I don't even understand what the
> error means.
