>             Project: Hive
>          Issue Type: Sub-task
>          Components: Spark
>    Affects Versions: spark-branch
>            Reporter: Chao

> The following query will not work:
> {code}
> from (select * from table0 union all select * from table1) s
> insert overwrite table table3 select s.x, count(1) group by s.x
> insert overwrite table table4 select s.y, count(1) group by s.y;
> {code}
> Currently, the plan for this query, before SplitSparkWorkResolver, looks like below:
> {noformat}
>    M1    M2
>      \  / \
>       U3   R5
>       |
>       R4
> {noformat}
> In {{SplitSparkWorkResolver#splitBaseWork}}, it assumes that the {{childWork}} is a ReduceWork, but for this case, you can see that for M2 the childWork could be UnionWork U3. Thus, the code will fail.
> HIVE-9041 addressed partially addressed the problem by removing union task. However, it's still necessary to cloning M1 and M2 to support multi-insert. Because M1 and M2 can run in a single JVM, the original solution of storing a global IOContext will not work because M1 and M2 have different io contexts, both needing to be stored.
