             Summary: Add New Methods for Comments in StructField and StructType
                 Key: SPARK-16157
                 URL: https://issues.apache.org/jira/browse/SPARK-16157
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Xiao Li


Currently, the column-related comment attribute is stored in {{Metadata}}. For example, 
{{noformat}}
StructType(
      StructField("cl1", IntegerType, nullable = false,
        new MetadataBuilder().putString("comment", "test").build()) :: Nil)
{{noformat}}

Compared with the existing SQL interface, it is not user friendly to add such a comment attribute when defining a {{StructField}}.
