Jason Altekruse resolved DRILL-2228.
------------------------------------
Resolution: Later
Flatten has been disabled in the order by clause by DRILL-2181. We will look at
how best to re-enable this past 1.0
> Projecting '*' returns all nulls when we have flatten in a filter and order by

> The below query returns all nulls currently :
> {code}
> 0: jdbc:drill:schema=dfs_eea> select * from `data.json` where 2 in (select
> flatten(lst_lst[1]) from `data.json`) order by flatten(lst_lst[1]);
> +------------+
> | * |
> +------------+
> | null |
> | null |
> | null |
> | null |
> | null |
> | null |
> | null |
> | null |
> | null |
> | null |
> +------------+
> {code}
> There seems to be another issue here since the no of records returned also
> does not look right. I will raise a separate JIRA for that.
> The issue goes away, if we do an order by without the flatten. Below query
> works
> {code}
> select * from `data.json` where 2 in (select flatten(lst_lst[1]) from
> `data.json`) order by uid;
> {code}
> Attached the data files
