Hi, I am trying to make a small poc on top of yarn.
Within the launched application master , I am trying to request for 50 containers and launch a same task on those allocated containers. My config : AM registration response minimumCapability {, memory: 1024, virtual_cores: 1, }, maximumCapability {, memory: 8192, virtual_cores: 32, }, 1) I am asking for 1G mem and 1 core container to the RM. Ideally the RM should return me 6 - 7 containers , but the response always returns with only 2 containers. Why is that ? 2) So , when in the first ask 2 containers are returned , then I again required the RM for 50 - 2 = 48 containers. I keep getting 0 containers , even if the previously started containers have finished. Why is that ? Any link explaining the allocate request of RM would be very helpful. Thanks, Rahul
