"Client mode" means the RPC env will not listen for incoming connections. This allows certain processes in the Spark stack (such as Executors or tha YARN client-mode AM) to act as pure clients when using the netty-based RPC backend, reducing the number of sockets needed by the app and also the number of open ports. Client connections are also preferred when endpoints that actually have a listening socket are involved; so, for example, if a Worker connects to a Master and the Master needs to send a message to a Worker endpoint, that client connection will be used, even though the Worker is also listening for incoming connections. With this change, the workaround for SPARK-10987 isn't necessary anymore, and is removed. The AM connects to the driver in "client mode", and that connection is used for all driver <-> AM communication, and so the AM is properly notified when the connection goes down. Author: Marcelo Vanzin <vanzin@cloudera.com> Closes #9210 from vanzin/SPARK-10997.
