------------------------------------
Summary: LAG function fails when selecting all columns
Key: SPARK-17049
URL: https://issues.apache.org/jira/browse/SPARK-17049
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.0.0
Reporter: Gokhan Civan
In version 1.6.1, the queries
create table a as select 1 as col;
select *, lag(col) over (order by col) as prev from a;
successfully produce the table
col prev
1 null
However, in version 2.0.0, this fails with the error
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;

On the other hand, the query works if * is replaced with col as in
select col, lag(col) over (order by col) as prev from a;
It also works as follows:
select col, lag(col) over (order by col ROWS BETWEEN 1 PRECEDING AND 1
PRECEDING) as prev from a;
