Sean Owen commented on SPARK-2445:
----------------------------------

[~gbowyer@fastmail.co.uk] are you saying that SPARK-3535 did actually resolve this?

>                 Key: SPARK-2445
>                 URL: https://issues.apache.org/jira/browse/SPARK-2445
>             Project: Spark
>          Issue Type: Bug
>          Components: Mesos
>    Affects Versions: 1.0.0
>            Reporter: Dario Rexin

> 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.
