Gera Shegalov commented on MAPREDUCE-6653:
------------------------------------------

In terms of user API we can introduce a new value for mapreduce.framework.name: yarn.local
or yarn.unmanaged.

> Long living DAG applications (pig, hive, etc) may launch many mapreduce jobs. Since we
already have to allocate resources for these clients, we could reduce the latency of monitoring
AM's, the overall number of network RPC's, the number of containers running on YARN cluster
by embedding the MRAppMaster with the submitter.
