Question

我正在运行一个多节点集群;我使用hadoop-1.0.3（两者都有），Hbase-0.94.2（两者都有）和zookeeper-3.4.6（只有主人）

主：192.168.0.1 从属：192.168.0.2

Hbase运行不正常，我在尝试在hbase上创建表时遇到了问题当然，我无法访问http://master:60010上的HBase状态用户界面，请帮助!!

以下是我的所有配置文件：

（hadoop conf）core-site.xml :(主服务器和从服务器上的配置相同）

 <configuration>
<property>
  <name>fs.default.name</name>
  <value>hdfs://localhost:54310</value>
 </property>
</configuration>

（hbase conf）hbase-site.xml：

<configuration>

<property>
      <name>hbase.rootdir</name>
      <value>hdfs://master:54310/hbase</value>
</property>

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

<property>
      <name>hbase.zookeeper.quorum</name>
      <value>master,slave</value>
</property>

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

<property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/usr/local/hadoop/zookeeper</value>
</property>

</configuration>

/ etc / hosts and：

192.168.0.1 master
192.168.0.2 slave

regionservers：

master
slave

这里是日志文件：hbase-hduser-regionserver-master.log

Answer 1

我认为localhost文件中的core-site.xml使用master。

将slave节点主机添加到hadoop目录中的slave文件中。

主人兼和从属节点core-site.xml文件如下所示：

<configuration>
<property>
  <name>fs.default.name</name>
  <value>hdfs://master:54310</value>
 </property>
</configuration>

如果你在两个文件中都有当前的zookeeper，那么

主服务器和从属主机应该存在于两个regionservers文件中。

Hbase连接问题并且无法创建表
