Description

Example

//We generate a schema object and call toString()
String schemaStr = "my_list: {array: (array_element: (num1: int,num2: int))}";
// Reparsed using org.apache.pig.impl.util.Utils
Schema schema = Utils.getSchemaFromString(schemaStr);
// But no longer matches the original structure
schema.toString();
// => {my_list: {array_element: (num1: int,num2: int)}}
