原因分析：

hbase我使用的自己搭建的zookeeper，而不是使用内嵌的zk.应该是zookeeper并没有创建/znode，所以就报错The node /hbase is not in ZooKeeper。

解决方法：

1.在master打开zookeeper客户端，创建znode

#./zkCli.sh

[zk: localhost:2181(CONNECTED) 0] create /hbase hbase
Created /hbase
[zk: localhost:2181(CONNECTED) 1]

2.然后检查hbase-site的配置zookeeper.znode.parent，改成和自己创建的一样

3.重启hbase,问题就解决了
