Subject [jira] [Created] (FLINK-3972) Subclasses of ResourceID may not to be serializable
Date Wed, 25 May 2016 15:18:12 GMT
Maximilian Michels created FLINK-3972:

             Summary: Subclasses of ResourceID may not to be serializable
                 Key: FLINK-3972
                 URL: https://issues.apache.org/jira/browse/FLINK-3972
             Project: Flink
          Issue Type: Bug
          Components: ResourceManager
    Affects Versions: 1.1.0
            Reporter: Maximilian Michels
            Assignee: Maximilian Michels
            Priority: Minor
             Fix For: 1.1.0

WorkerTypes are currently subclasses of ResourceID. ResourceID has to be Serializable but
its subclasses don't. This may lead to problems when these subclasses are used as ResourceIDs,
i.e. serialization may fail with NotSerializableExceptions. Currently, subclasses are never
send over the wire but they might be in the future.

Instead of relying on subclasses of ResourceID for the WorkerTypes, we can let them implement
an interface to retrieve the ResourceID of a WorkerType.
