Blocker Description
When we use a reference from Dataset in filter or sort, which was not used in the prior select, an AnalysisException occurs, e.g.,
val df = Seq(("test1", 0), ("test2", 1)).toDF("name", "id") df.select(df("name")).filter(df("id") === 0).show()
org.apache.spark.sql.AnalysisException: Resolved attribute(s) id#6 missing from name#5 in operator !Filter (id#6 = 0).;;
!Filter (id#6 = 0)
+- AnalysisBarrier
+- Project [name#5]
+- Project [_1#2 AS name#5, _2#3 AS id#6]
+- LocalRelation [_1#2, _2#3]
If we use col instead, it works:
val df = Seq(("test1", 0), ("test2", 1)).toDF("name", "id") df.select(col("name")).filter(col("id") === 0).show()
