> Exception when Joining dataframe with another dataframe generated by applying
> groupBy transformation on original one
> --------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-20093
> URL: https://issues.apache.org/jira/browse/SPARK-20093
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0, 2.0.1, 2.0.2, 2.1.0, 2.2.0
> Reporter: Hosur Narahari
>
> When we generate a dataframe by doing grouping, and perform join on original
> dataframe with aggregate column, we get AnalysisException. Below I've
> attached a piece of code and resulting exception to reproduce.
> Code:
> import org.apache.spark.sql.SparkSession
> object App {
> lazy val spark =
> SparkSession.builder.appName("Test").master("local").getOrCreate
> def main(args: Array[String]): Unit = {
> test1
> }
> private def test1 {
> import org.apache.spark.sql.functions._
> val df = spark.createDataFrame(Seq(("M",172,60), ("M", 170, 60), ("F",
> 155, 56), ("M", 160, 55), ("F", 150, 53))).toDF("gender", "height", "weight")
> val groupDF = df.groupBy("gender").agg(min("height").as("height"))
> groupDF.show()
> val out = groupDF.join(df, groupDF("height") <=>
> df("height")).select(df("gender"), df("height"), df("weight"))
> out.show
> }
> }
> When I ran above code, I got below exception:
> Exception in thread "main" org.apache.spark.sql.AnalysisException: resolved
> attribute(s) height#8 missing from
> height#19,height#30,gender#29,weight#31,gender#7 in operator !Join Inner,
> (height#19 <=> height#8);;
> !Join Inner, (height#19 <=> height#8)
> :- Aggregate [gender#7], [gender#7, min(height#8) AS height#19]
