---------------------------------

I'm not using Spark currently, you can close it as you wish.

>                 Key: SPARK-3334
>                 URL: https://issues.apache.org/jira/browse/SPARK-3334
>             Project: Spark
>          Issue Type: Bug
>          Components: Mesos
>    Affects Versions: 1.0.2
>         Environment: Mesos 0.16.0/0.19.0
> CentOS 6.4
>            Reporter: Iven Hsu
>
> The {{akkaFrameSize}} is set to {{Long.MaxValue}} in MesosBackend to workaround SPARK-1112,
this causes all serialized task result is sent using Mesos TaskStatus.
> mesos-master stores TaskStatus in memory, and when running Spark, its memory grows very
fast, and will be OOM killed.
> See MESOS-1746 for more.
> I've tried to set {{akkaFrameSize}} to 0, mesos-master won't be killed, however, the
driver will block after success unless I use {{sc.stop()}} to quit it manually. Not sure if
it's related to SPARK-1112.
