Description

This currently doesn't work because Player depends on Position, but it should:

$ cat position.avsc 
{"type":"enum", "name": "Position", "namespace": "avro.examples.baseball",
    "symbols": ["P", "C", "B1", "B2", "B3", "SS", "LF", "CF", "RF", "DH"]
}

$ cat player.avsc 
{"type":"record", "name":"Player", "namespace": "avro.examples.baseball",
  "fields": [
   {"name": "number", "type": "int"},
   {"name": "first_name", "type": "string"},
   {"name": "last_name", "type": "string"},
   {"name": "position", "type": {"type": "array", "items": "avro.examples.baseball.Position"} }
  ]
}

$ cat baseball.avdl 
@namespace("avro.examples.baseball")
protocol Baseball {
   import schema "position.avsc";
   import schema "player.avsc";
}

$ java -jar avro-tools-1.5.1.jar idl baseball.avdl baseball.avpr
