> After the configured number of retries SplitLogManager is not going to resubmit log-split
tasks. In this situation even if the splitLogWorker that owns the task dies the task will
not get resubmitted.
> When a regionserver goes away then all the split-log tasks that it owned should be resubmitted
by the SplitLogMaster.
