> When multiple instances of the MesosExecutorBackend are running on the same slave, they will have the same executorId assigned (equal to the mesos slaveId), but will have a different port (which is randomly assigned). Because of this, it can not register a new BlockManager, because one is already registered with the same executorId, but a different BlockManagerId.
