如若启动方式采用如下形式：
# start-hbase.sh发现master和region都起来了，但master中日志中一直打印如下日志：
2017-03-13 17:00:39,368 INFO [d721:60000.activeMasterManager] master.ServerManager: Waiting for region servers count to settle; currently checked in 0, slept for 15204 ms, expecting minimum of 1, maximum of 2147483647, timeout of 4500 ms, interval of 1500 ms.正确启动应当如下：
$ hbase-daemon.sh start master ####等待20秒左右
$ hbase-daemon.sh start regionserver 注：hadoop安全管理相关教程：
