解决办法:
- (清除hbase原有的所有数据)
1、hadoop的bin目录下,执行命令以下命令清除Hbase数据
hadoop fs -rm -r /hbase
2、连接ZK,执行以下命令清除Hbase数据
[link999@hadoop102 zookeeper]$ bin/zkCli.sh -server 127.0.0.1:2181
deleteall /hbase
3、重启ZK、重启hadoop(hdfs、yarn)、重启hbase
之后可以正常使用
如果是下面这个报错,也可以尝试以上的方法
- ERROR: Can’t get master address from ZooKeeper; znode data == null
