hadoop - 节点/hbase 不在 ZooKeeper 中

Question

我是 Hadoop 的新手，尝试以伪分布式模式安装 Hbase，版本为 hbase-0.98.10.1-hadoop1-bin，Hadoop 2.5.2。我无法添加表格。

当我尝试创建表时，以下错误继续存在:

client.HConnectionManager$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.

最终在显示错误多次(大约 50 次)后给出最终错误为:

ERROR: 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.

可能的错误是什么？感谢您的帮助。

在使用不同的 hbase 版本后它就可以工作了。我使用的是 hbase-0.98.10.1-hadoop1-bin，它与我的 hadoop 2.5.2 不兼容，所以我将 hbase 版本更改为 hbase-X.XX.XX.X-hadoop2-bin(与 hadoop 2 兼容) .X ) 并遵循 Apache 的安装步骤。谢谢大家..
