Hyukjin Kwon resolved SPARK-15941.
----------------------------------
Resolution: Incomplete
> Netty RPC implementation ignores the executor bind address
> ----------------------------------------------------------
>
> Key: SPARK-15941
> URL: https://issues.apache.org/jira/browse/SPARK-15941
> Project: Spark
> Issue Type: Bug
> Affects Versions: 1.6.1
> Reporter: Marco Capuccini
> Priority: Major
> Labels: bulk-closed
>
> When using Netty RPC implementation, which is the default one in Spark 1.6.x,
> the executor addresses that I see in the Spark application UI (the one on
> port 4040) are the IP addresses of the machines, even if I start the slaves
> with the -H option, in order to bind each slave to the hostname of the
> machine.
> This is a big deal when using Spark with HDFS, as the executor addresses need
> to match the hostnames of the DataNodes, to achieve data locality.
> When setting spark.rpc=akka everything works as expected, and the executor
> addresses in the Spark UI match the hostname, which the slaves are bound to.
