-------------------------------
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}
