> When HDFS is starting up, it starts in safe mode until the NN is able to read the whole fs image and initialize everything. For a really large NN that can take a while.
> If the HS is started at the same time, it may give up trying to check whether the event log directory exists, and exit. That's a little sub-optimal; the HS could wait until HDFS came out of safe mode instead.
