>             Project: Hive
>          Issue Type: Bug
>          Components: Spark
>            Reporter: Xuefu Zhang
>            Assignee: Jimmy Xiang
>             Fix For: spark-branch
>         Attachments: HIVE-9492.1-spark.patch, HIVE-9492.2-spark.patch, prototype.patch
> Because of the IOContext problem (HIVE-8920, HIVE-9084), RDD caching is currently disabled
in MapInput. Prototyping shows that the problem can solved. Thus, we should formalize the
prototype and enable the caching. A good query to test this is:
> {code}
> from (select * from dec union all select * from dec2) s
> insert overwrite table dec3 select, sum(s.value) group by
> insert overwrite table dec4 select, s.value order by s.value;
> {code}
