hbase ERROR: Can't get master address from ZooKeeper; znode data == null問題解答

當啓動hbase後查看日誌出現相似下面的錯誤日誌，而且hbase shell進入hbase後，list下會出現

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

解決方法：刪除各個節點hbase自動生成的zookeeper文件（當使用的zookeeper時habse自帶的時候），如果不能夠還能夠再嘗試將hadoop中hbase的的目錄刪除（啓動hadoop先，hadoop fs -rm -r /hbase）
