> Currently, we are using {{sql}} to print the schema. To make the schema more readable, we should use {{treeString}}, like what we did in Dataset API {{printSchema}}
> Below is the current way:
> {noformat}
> Schema: STRUCT<`a`: STRING (nullable = true), `b`: INT (nullable = true), `c`: STRING (nullable = true), `d`: STRING (nullable = true)>
> {noformat}
> After the change, it should look like
> {noformat}
> Schema: root
>  |-- a: string (nullable = true)
>  |-- b: integer (nullable = true)
>  |-- c: string (nullable = true)
>  |-- d: string (nullable = true)
> {noformat}
