Hi I'm doing some research on MRv2. It would be very helpful for you to answer this question.
As RMContainerAllocator allocates resource for MRv2 job. The state of task is pending, scheduled, assigned, completed. When task transfers from assigned to completed queue? I think when NM tells RM that a container finishes, and MRAM sends a heartbeat to RM, RM tells the MRAM that the container finishes, then the task of the container transfers from assigned to completed. Am I right
