> Labels: pull-request-available, stale-assigned

> Currently SQL client does not show arrays/map in human readable way (please
> have a look at examples below). e.g. {code}select map[1,2];{code} is shown as
> {noformat} +/- EXPR$0
> + java.util.HashMap
> {noformat}
> {code}select array[1,2];{code} is shown as {noformat}
> +/- EXPR$0
> + java.lang.Integer[]
> {noformat}
> {code}select array[map[1,2],map[2,2]];{code} is shown as {noformat} +/-
> EXPR$0
> + java.util.Map[]{noformat}
> {code}select map[array[1,2], array[1,2]];{code} is shown as {noformat} +/-
> EXPR$0
> + java.util.HashMap{noformat}
