I've noticed the jira page: https://issues.apache.org/jira/browse/AVRO-803, and known how to generate a Map<String, MyType> class using a schema file.
In my case, the schema file is “MyType.avsc”, and I used avro-tools to generate a "MyType.java" class, My question is how to dynamically create a MapSchema of Map<String, MyType>, since I have to Ser/De a Map<String, MyType>. I tried to use the method Schema.createMap(Schema myType), but the key is "Utf8" not "String".
