             Summary: Use treeString to print out the table schema for CatalogTable
                 Key: SPARK-20067
                 URL: https://issues.apache.org/jira/browse/SPARK-20067
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.1.0
            Reporter: Xiao Li
            Assignee: Xiao Li


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}
