Thank you for the catch.
Corrected
> Deep toString for arrays/map in SQL client
> -------------------------------------------
>
> Key: FLINK-9696
> URL: https://issues.apache.org/jira/browse/FLINK-9696
> Project: Flink
> Issue Type: Bug
> Components: Table API & SQL
> Reporter: Sergey Nuyanzin
> Assignee: Sergey Nuyanzin
> Priority: Major
> Labels: pull-request-available
>
> 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}
