[jira] [Commented] (SPARK-3334) Spark causes mesos-master memory leak

["Iven Hsu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-3334?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14168999#comment-14168999 ] 

Iven Hsu commented on SPARK-3334:
---------------------------------

With spark 1.1.0, {{akkaFrameSize}} is same as other backends, reading from configuration. But the minimum value of it is 32000, and can't be set to 0, so it will still cause mesos-master to leak memory.

Anyone look into this?

>             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.
