Rahul Challapalli reopened DRILL-2754:
--------------------------------------

Though we have a unit test for this, I am getting the below ouput from sqlline. There could be some issue with JDBC

0: jdbc:drill:schema=dfs_eea> select flatten(config) from `json_kvgenflatten/DRILL-2754.json`;

> {code}
> {
>      "config": [
>          [],
>          [ "a string" ]
>      ]
> }
> {code}
> {code}
> select flatten(config) as flat from cp.`/store/json/null_list.json`
> {code}
> This was carved out of a larger use case that was failing, so in the course of coming up with a minimal reproduction I fixed the bug. I will be posting a patch shortly.
