Question

我正在一对Linux服务器上尝试双节点hbase集群。所有文件都被转移，服务器上有一个正在运行的hadoop集群，但是hbase仍然拒绝完全工作。 zookeepers和region服务器正常启动，我甚至可以使用shell但是master拒绝启动。主服务器的日志原因如下：

我的hbase-site.xml的配置是

<configuration>
<property>
<name>hbase.master</name>
<value>master:60000</value>
</property>

<property>
<name>hbase.rootdir</name>
<value>hdfs://hadoop-namenode:9000/hbase</value>
</property>


<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>



<property>
     <name>hbase.zookeeper.property.clientPort</name>
   <value>2222</value>
 </property>


<property>
<name>hbase.zookeeper.quorum</name>
<value>master</value>
</property>
</configuration>

我的配置有问题，还是网络问题？

Answer 1

HBase master无法解析“hadoop-namenode”的ip。您是否已在主计算机的/etc/hosts文件中添加了“hadoop-namenode”。您可以通过HBase主计算机中的ping hadoop-namenode轻松检查它。
