    @arina-ielchiieva  have passed all the unit tests under java-exec bundle , 
got some errors which are sure not associated with this change, maybe my branch 
was old from the master.

    I also found the error to do `mvn test` ,got the same error as JIRA 
DRILL-4104 . through `mvn test -pl exec/java-exec` this method,I got the unit 
test result. I wonder how the devs do the test result .

>                 URL: https://issues.apache.org/jira/browse/DRILL-5691
>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Execution - Relational Operators
>    Affects Versions: 1.9.0, 1.10.0
>            Reporter: weijie.tong
> I materialized the count distinct query result in a cache , added a plugin 
> rule to translate the (Aggregate、Aggregate、Project、Scan) or 
> (Aggregate、Aggregate、Scan) to (Project、Scan) at the PARTITION_PRUNING phase. 
> Then ,once user issue count distinct queries , it will be translated to query 
> the cache to get the result.
> eg1: " select count(*),sum(a) ,count(distinct b)  from t where dt=xx " 
> eg2:"select count(*),sum(a) ,count(distinct b) ,count(distinct c) from t 
> where dt=xxx "
> eg3:"select count(distinct b), count(distinct c) from t where dt=xxx"
> eg1 will be right and have a query result as I expected , but eg2 will be 
> wrong at the physical phase.The error info is here: 
> https://gist.github.com/weijietong/1b8ed12db9490bf006e8b3fe0ee52269. 
> eg3 will also get the similar error.
