Hbase学习笔记二：解决ERROR: Can't get master address from ZooKeeper; znode data == null

问题描述

运行Hbase shell时报错：
hbase(main):006:0> list
TABLE                                                                                                                                                                   


ERROR: Can't get master address from ZooKeeper; znode data == null


Here is some help for this command:
List all tables in hbase. Optional regular expression parameter could
be used to filter the output. Examples:


  hbase> list
  hbase> list 'abc.*'
  hbase> list 'ns:abc.*'
  hbase> list 'ns:.*'

解决方法

原因：运行hbase(zookeeper)的用户无法写入zookeeper文件，导致znode data为空
解决如下：
格式化hdfs  进入Hadoop/bin 目录下 : ./hadoop namenode –format
启动 zookeeper
启动 hadoop 
启动 hbase 

进入hbase shell 成功，执行list如下：

hbase shell
