我是一个hadoop新手，尝试以伪分布式模式安装hbase，版本hbase-0.98.10.1-hadoop1-bin和hadoop2.5.2。我无法添加表。
尝试创建表时继续出现以下错误：

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.

在多次（大约50次）显示错误后，最终给出的错误如下：

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.

这意味着zookeeper没有节点'/hbase'，因此在zookeeper中创建一个节点名'/hbase'。转到zkcli并运行'create/hbase''命令。

我在talend中使用它，当我在hadoop集群中添加hbase连接时，步骤2/2，我在hadoop集群中选择repository，当我写入服务器和端口（默认2181）时，点击按钮“check”，系统提示：
连接失败。必须更改数据库设置。原因：org.apache.hadoop.hbase.masternotrunningexception:节点/hbase不在zookeeper中。应该是大师写的。检查“zookeeper.znode.parent”中配置的值。可能与主服务器中配置的不匹配
然后，需要添加hadoop属性，单击按钮并添加到属性
zookeeper.znode.parent=/hbase unsecure单击“确定”，然后单击“检查”，系统提示成功。

确保zookeeper应该是start，datadir应该存在。

它只是在使用了不同的hbase版本之后才起作用。我使用的是hbase-0.98.10.1-hadoop1-bin，它与我的hadoop2.5.2不兼容，因此我将hbase版本更改为hbase-x.xx.xx.x-hadoop2-bin（它与hadoop2.x兼容），并遵循apache的安装步骤。谢谢大家。。

上面的答案是正确的，但要长一点。我可以通过在hbase-site.xml（使用hbase-1.2.1）中添加以下属性来解决这个问题

<property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/mnt/data/zookeeper</value>
</property>

我也不必创建/mnt/data/zookeeper。由于我使用hbase作为一个独立的，我没有运行zookeeper事实上它给了一个错误，当我这样做
完整的hbase-site.xml配置文件如下所示

<configuration>
    <property>
        <name>hbase.rootdir</name>
        <value>file:///mnt/data/hbase</value>
    </property>
   <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/mnt/data/zookeeper</value>
   </property>
</configuration>
