> After HDFS-4840, TestNNThroughputBenchmark exits in the middle. This is because ReplicationMonitor
is being stopped while NN is still running. 
> This is only valid during testing. In normal cases, ReplicationMonitor thread runs all
the time once started. In standby or safemode, it just skips calculating DN work. I think
NNThroughputBenchmark needs to use ExitUtil to prevent termination, rather than modifying
ReplicationMonitor.
