Lefty Leverenz commented on HIVE-12568:
---------------------------------------
HIVE-12940 merged this to master for release 2.1.0, so I added a TODOC2.1 label.
Ping for the doc question: Should *hive.spark.client.rpc.server.address* be
mentioned in Hive on Spark: Getting Started?
> Provide an option to specify network interface used by Spark remote client
> [Spark Branch]

> Spark client sends a pair of host name and port number to the remote driver
> so that the driver can connects back to HS2 where the user session is. Spark
> client has its own way determining the host name, and pick one network
> interface if the host happens to have multiple network interfaces. This can
> be problematic. For that, there is parameter,
> hive.spark.client.server.address, which user can pick an interface.
> Unfortunately, this interface isn't exposed.
> Instead of exposing this parameter, we can use the same logic as Hive in
> determining the host name. Therefore, the remote driver connecting to HS2
> using the same network interface as a HS2 client would do.
> There might be a case where user may want the remote driver to use a
> different network. This is rare if at all. Thus, for now it should be
> sufficient to use the same network interface.
