> 1. "n1.json" is :
> {code}
> {"test":[1,2,3,4,4,5]}
> {code}
> Then the function works fine:

> 0: jdbc:drill:> select repeated_count(t.test) from `n1.json` as t;
> +------------+
> |   EXPR$0   |
> +------------+
> | 6          |

> 2. However if the json has 2-level or more arrays:
> {code}
> {"test":[[1,2,3,4,5,6]]}
> {code}
> The function failed:
> {code}
> 0: jdbc:drill:> select t.test[0][0],t.test[0][1] from `n4.json` as t;
