可能的原因如下：
1. 时间没有同步
HBase需要结点间的时间必须是同步的，可以使用date命令在Linux查看时间（同步时间命令：ntpdate 1.cn.pool.ntp.org）
2. 底层采用的不是hdfs协议
这个可以通过查看hbase-site.xml中参数hbase.rootdir的值来群定，一些其它的协议比如file协议等等，
HBase也 是支持的
3. ZooKeeper
1) 查看zookeeper的状态是否正常，可以使用 zkServer.sh status 查看状态，或者直接查看它的日志
2) 如果zookeeper的状态正常，很有可能就是防火墙阻挡了zookeeper的默认端口2181
实际解决方法：
