There is another bug when reading such schema:
```thrift
required group list_of_maps (LIST) {
repeated group array (MAP) {
repeated group key_value (MAP_KEY_VALUE) {
required binary key (STRING);
required binary value (STRING);
}
}
}
```
```java
Schema schema = new Schema.Parser().parse("{"
+ "\"type\":\"record\","
+ "\"name\":\"complex_record\","
+ "\"fields\":["
+ " {\"name\":\"list_of_maps\", \"type\":{\"type\":\"array\",
\"items\":{\"type\":\"map\", \"values\":\"string\"}}}"
+ "]"
+ "}");
// list<map<string,string>>
// We create a GenericData.Array using the schema for the 'list_of_maps'
field
Schema listOfMapsSchema = schema.getField("list_of_maps").schema();
record.put("list_of_maps", new GenericData.Array<Map<String, String>>(2,
listOfMapsSchema) {
{
add(new HashMap<String, String>() {
{
put("listKey1", "listVal1");
}
});
add(new HashMap<String, String>() {
{
put("listKey2", "listVal2");
}
});
}
});
```
