----------------------------------
[~gbow...@fastmail.co.uk] are you saying that SPARK-3535 did actually resolve
this?
> MesosExecutorBackend crashes in fine grained mode
> -------------------------------------------------
>
> 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.
> More description and a fix can be found in this PR on GitHub:
> https://github.com/apache/spark/pull/1358
