ERROR: Can't get master address from ZooKeeper; znode data == null 一定注意这只是问题的第一层表象，真的问题是：
File /hbase/.tmp/hbase.version could only be replicated to 0 nodes instead of minReplica
网上很多都是叫用两种方式解决
- stop/start 重启hbase
- 格式化 hdfs namenode -format，不能随随便便就格式话hadoop的namenode
按照上述方式试一两个小时找问题，没有找到，最后问题就在每个应用的日志里藏着
Hbase中启动中很多异常的坑会遇到，但是请一定不要慌，坑多是因为我们对她不熟悉，我找了一上午的错误例子，在今年5月份我记得我可以启动单机的hbase hadoop zookeeper，由于我的阿里云服务器要用作别用，我就关闭了三个应用，9月我再次启动时，就不能启动了。
org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /hbase/.tmp/hbase.version could only be replicated to nodes instead of minReplication (=). There are datanode(s) running and no node(s) are excluded in this operation.

我打开hbase hadoop zookeeper 三者中data缓存文件，里面还是5月份的数据，比较坑就是每次重启都不自己覆盖以前的文件的么。这里就以后不要用kill 去关掉线程了
[root@app hbase-1.2.-cdh5.10.0]# cd data/tmp/
重新启动 hbase hadoop zookeeper 进入 hbase shell命令客户端
[root@app bin]# ./hbase shell

最后强调一下jps 查看最近启动的进程中是不是全部启动，我这里是单机版的，仅供参考。
