The node /hbase-unsecure is not in ZooKeeper.

首先先确认您的Hadoop版本与Hbase是否兼容，否则一切都是扯淡
各hbase版本对hadoop各版本的支持情况

之前以为单机式Hadoop不需要配置hbase.cluster.distributed，遂在hbase-site.xml中将其删除导致以下错误：

2016-08-15 23:20:36,028 ERROR [main] client.ConnectionManager$HConnectionImplementation: The node /hbase-unsecure is not in ZooKeeper. It shoulne configured in the master.

或者

2016-08-15 22:53:06,127 ERROR [main] client.ConnectionManager$HConnectionImplementation: The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

解决方法：
将hbase-site.xml修改如下：

验证：
1.启动HBASE
2.JPS
