the -1 might be the problem, it should be 4096 and the vCores should be 1
instead of 0.
I tried several times, if the log has only one <memory:-1, vCores:0>, the
reserved memory will be 4G after all the jobs done, and if the log has two
<memory:-1, vCores:0>, the reserved memory will be 8G after all the jobs done.
> With Fair Scheduler, reserved MB reported in RM web UI increases indefinitely
