Arseniy Tashoyan commented on SPARK-21668:
------------------------------------------
I don't think it is a duplicate of [ SPARK-6680 ]. The referenced issue covers
a very specific environment: all Docker containers are on the same machine,
hence in the same bridged network.
This issue covers a more generic setup: a container with a driver program and a
real Spark cluster.
The solution proposed in [ SPARK-6680 ] does not work for this case - specify
--conf spark.driver.host=${SPARK_LOCAL_IP}. The process inside the container
cannot bind to the IP address of the host machine.

> Key: SPARK-21668
> URL: https://issues.apache.org/jira/browse/SPARK-21668
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.1.1, 2.2.0
> Reporter: Arseniy Tashoyan
> Priority: Minor
> Labels: containers, docker, driver, spark-submit, standalone
> Original Estimate: 96h
> Remaining Estimate: 96h

> When a driver program in Client mode runs in a Docker container, it binds to
> the IP address of the container, not the host machine. This container IP
> address is accessible only within the host machine, it is inaccessible for
> master and worker nodes.
> For example, the host machine has IP address 192.168.216.10. When Docker
> machine starts a container, it places it to a special bridged network and
> assigns it an IP address like 172.17.0.2. All Spark nodes belonging to the
> 192.168.216.0 network cannot access the bridged network with the container.
> Therefore, the driver program is not able to communicate with the Spark
> cluster.
> Spark already provides SPARK_PUBLIC_DNS environment variable for this
> purpose. However, in this scenario setting SPARK_PUBLIC_DNS to the host
> machine IP address does not work.
