Jeff Zhang commented on SPARK-6653:
-----------------------------------
Although this is already committed, would it be better to specify a port range ?
> New configuration property to specify port for sparkYarnAM actor system
> -----------------------------------------------------------------------
>
> Key: SPARK-6653
> URL: https://issues.apache.org/jira/browse/SPARK-6653
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 1.3.1
> Environment: Spark On Yarn
> Reporter: Manoj Samel
> Assignee: Shekhar Bansal
> Priority: Minor
> Fix For: 1.4.0
>
>
> 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
