java.lang.RuntimeException : Failed construction of Master: class org. apache.hadoop.hbase.master.HMaster

Question

当我启动-hbase.sh

HMaster 和 HregionServer 正在启动，但一段时间后不可见。

通过查看日志，我发现了这一点。

HMaster:

我的 Hbase-site.xml:

  <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
 </property>
 <property>
   <name>hbase.rootdir</name>
   <value>hdfs://localhost:9000/hbase</value>
 </property>
 <property>
    <name>hbase.zookeeper.quorum</name>
    <value>hdfs://localhost</value>
 </property>

 </configuration>

我的 core-site.xml

   <property>
     <name>fs.default.name</name>
     <value>hdfs://CentOS64:9000</value>
   </property>

   <property>
     <name>hadoop.tmp.dir</name>
     <value>/root/hadoop/tmp</value>
   </property>


 </configuration>

我的主机:

192.168.79.10 CentOS64 本地主机

我试过 CentOS64，也给了 ip，还是一样的问题。

请帮帮我。

Answer 1

属性 hbase.zookeeper.quorum 接受

Comma separated list of servers in the ZooKeeper Quorum.

修改属性值并重启Hbase服务，

 <property>
    <name>hbase.zookeeper.quorum</name>
    <value>localhost</value>
 </property>

从您的其他配置属性来看，设置看起来像伪分布式，对于本地和伪分布式操作模式，默认设置为 localhost。对于这些模式，您可以从 hbase-site.xml 中省略此属性。

否则，将 Zookeeper 服务器的完整列表作为逗号分隔的服务器添加到此属性。
