yan tianxing created SPARK-7428:
-----------------------------------
Summary: DataFrame.join() could create a new df with duplicate
column name
Key: SPARK-7428
URL: https://issues.apache.org/jira/browse/SPARK-7428
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.3.0
Environment: spark-1.3.0-bin-hadoop2.4
Reporter: yan tianxing
>val df = sc.parallelize(Array(1,2,3)).toDF("x")
>val df2 = sc.parallelize(Array(1,4,5)).toDF("x")
>val df3 = df.join(df2,df("x")===df2("x"),"inner")
>df3.show
x x
1 1
> df3.select("x")
org.apache.spark.sql.AnalysisException: Ambiguous references to x:
(x#1,List()),(x#3,List());
