Description

In https://issues.apache.org/jira/browse/SPARK-19830, we add a new API in the DDL parser to convert a DDL string into a schema. Then, we can use DDL formats in existing some APIs, e.g., functions.from_json https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/functions.scala#L3062.
