             Summary: Using flatten in a project, filter (where in ...), and order by throws an ClassCastException
                 Key: DRILL-2227
                 URL: https://issues.apache.org/jira/browse/DRILL-2227
             Project: Apache Drill
          Issue Type: Bug
          Components: Functions - Drill
            Reporter: Rahul Challapalli
            Assignee: Jason Altekruse


git.commit.id.abbrev=3d863b5

The below query fails :
{code}
select uid, flatten(lst_lst[0]) from `data.json` where 2 in (select flatten(lst_lst[1]) from `data.json`) order by flatten(lst_lst[1]);

Query failed: RemoteRpcException: Failure while running fragment., org.apache.drill.exec.vector.BigIntVector cannot be cast to org.apache.drill.exec.vector.RepeatedVector 
{code}

However if we apply flatten on the same column in the "select" part, it succeeds
{code}
0: jdbc:drill:schema=dfs_eea> select uid, flatten(lst_lst[1]) from `data.json` where 2 in (select flatten(lst_lst[1]) from `data.json`) order by flatten(lst_lst[1]);
