All Implemented Interfaces:

Closeable, AutoCloseable, org.apache.hadoop.service.Service

public class LocalDAGAppMaster
extends DAGAppMaster

A DAGAppMaster implementation which is really local in a sense that it doesn't start an RPC server for handling dag requests. It is typically used by LocalClient, which already has an embedded DAGAppMaster, but by default, it calls RPC methods. With tez.local.mode.without.network=true, LocalClient will call the DAGAppMaster's methods directly.
