----------------------------------------
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]);
