Jeff Zhang commented on SPARK-6653:
-----------------------------------

Although this is already committed, would it be better to specify a port range ?

>          Components: YARN
>    Affects Versions: 1.3.1
>         Environment: Spark On Yarn
>            Reporter: Manoj Samel

> In 1.3.0 code line sparkYarnAM actor system is started on random port. See org.apache.spark.deploy.yarn ApplicationMaster.scala:282
> actorSystem = AkkaUtils.createActorSystem("sparkYarnAM", Utils.localHostName, 0, conf = sparkConf, securityManager = securityMgr)._1
> This may be issue when ports between Spark client and the Yarn cluster are limited by firewall and not all ports are open between client and Yarn cluster.
> Proposal is to introduce new property spark.am.actor.port and change code to
> val port = sparkConf.getInt("spark.am.actor.port", 0)
>     actorSystem = AkkaUtils.createActorSystem("sparkYarnAM", Utils.localHostName, port,
>       conf = sparkConf, securityManager = securityMgr)._1
