use bucketed table (was: Bucket column only need to be found in the output
relation when use bucketed table)

> bucketed table

> Key: SPARK-15549
> URL: https://issues.apache.org/jira/browse/SPARK-15549
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Yadong Qi
>
> I create a bucketed table test(i int, j int, k int) with bucket column i,
> {code:java}
> case class Data(i: Int, j: Int, k: Int)
> sc.makeRDD(Array((1, 2, 3))).map(x => Data(x._1, x._2,
> x._3)).toDF.write.bucketBy(2, "i").saveAsTable("test")
> {code}
> and I run the following SQL:
> {code:sql}
> SELECT j FROM test;
> Error in query: bucket column i not found in existing columns (j);
> SELECT j, MAX(k) FROM test GROUP BY j;
> Error in query: bucket column i not found in existing columns (j, k);
> {code}
> I think the bucket column only need to be found in the output of relation. So
> the 2 sqls bellow should be executed right.
