> The NM state machines can make the following two invalid state transitions when a speculative attempt is killed shortly after it gets started. When this happens the NM keeps the log aggregation context open for this application and therefore chews up FDs and leases on the NN, eventually running the NN out of FDs and bringing down the entire cluster.
