Xiangrui Meng updated SPARK-27368:
----------------------------------
Description:
Design draft:
Scenarios:
* client-mode, worker might create one or more executor processes, from
different Spark applications.
* cluster-mode, worker might create driver process as well.
* local-cluster model, there could be multiple worker processes on the same
node. This is an undocumented use of standalone mode, which is mainly for tests.
Because executor and driver processes on the same node will share the
accelerator resources, worker must take the role that allocates resources. So
we will add spark.worker.resource.[resourceName].discoveryScript conf for
workers to discover resources. User need to match the resourceName in driver
and executor requests and they don't need to specify discovery scripts
separately.
