> Rollup produces incorrect results when group clause contains an expression
> {code}case class KeyValue(key: Int, value: String)
> val df = sc.parallelize(1 to 50).map(i=>KeyValue(i, i.toString)).toDF
> df.registerTempTable("foo")
> sqlContext.sql(“select count(*) as cnt, key % 100 as key,GROUPING__ID from foo group by key%100 with rollup”).show(100)
> {code}
> As a workaround, this works correctly:
> {code}
> val df1=df.withColumn("newkey",df("key")%100)
> df1.registerTempTable("foo1")
> sqlContext.sql("select count(*) as cnt, newkey as key,GROUPING__ID as grp from foo1 group by newkey with rollup").show(100)
> {code}
