Hi, I am trying to understand how the resource allocation happens in spark. I understand the resourceOffer method in taskScheduler. This method takes care of locality factor while allocating the resources. This resourceOffer method gets invoked by the corresponding cluster manager.
I am working on stand-alone spark cluster. But I am not able to locate starting point of the resource allocation. I want to understand from end to end how exactly resource allocations happens, given a new Application to the Spark. Also, apart from mesos, there is a folder called Local in the Scheduler. Can someone tell me which all files should I look into to understand the resource allocation in stand-alone spark cluster and what is this "Local" for? Thanks in advance!! Karthik.
