[SPARK-11020] [core] Wait for HDFS to leave safe mode before initializing
HS.
Large HDFS clusters may take a while to leave safe mode when starting; this
change
makes the HS wait for that before doing checks about its configuraton. This
means
the HS won't stop right away if HDFS is in safe mode and the configuration
is not
correct, but that should be a very uncommon situation.
