----------------------------------

             Summary: When parsing a schema, pig drops tuple inside of Bag if 
it contains only one field
                 Key: PIG-4219
                 URL: https://issues.apache.org/jira/browse/PIG-4219
             Project: Pig
          Issue Type: Bug
            Reporter: Julien Le Dem


Example
{code:java}
//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)}}
{code}
