----------------------------------
errors logs:
> Run count(distinct name) from sub query found some errors
> ---------------------------------------------------------
>
> Key: SPARK-19037
> URL: https://issues.apache.org/jira/browse/SPARK-19037
> Project: Spark
> Issue Type: Bug
> Components: Spark Shell, SQL
> Affects Versions: 2.1.0
> Environment: spark 2.1.0, scala 2.11
> Reporter: J.P Feng
> Labels: distinct, sparkSQL, sub-query
>
> when i use spark-shell or spark-sql to execute count(distinct name) from
> subquery, some errors occur:
> select count(distinct name) from (select * from mytest limit 10) as a
> if i do this in hive-server2, i can get the correct result.
> if i just execute select count(name) from (select * from mytest limit 10) as
> a, i can also get the right result.
> besides, i found the same errors when i use max(), distinct(),groupby() with
> subquery.
> I think there maybe some bugs when doing key-reduce jobs with subquery.
> I will add the errors in new comment.
