大家好，我在主日志中运行HBase时遇到此异常而HMaster未运行。

我搜索了很多但无法找到解决方案。这是我的/ etc / hosts文件

127.0.0.1   localhost hbase-system
23.21.190.123   hbase.com.com hbase localhost


我甚至通过评论localhost条目i-e＃127.0.0.1 localhost尝试了它，但是无法运行HMaster。 这是我的hbase-site.xml 

<configuration>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:54310/hbase</value>
</property>

这是我的hadoop core-site.xml 

<configuration>
<property>
<name>hadoop.tmp.dir</name>
<value>/app/hadoop/tmp</value>
</property><property>
<name>fs.default.name</name>
<value>hdfs://localhost:54310</value>
</property>
</configuration>

如果有人遇到问题，请帮帮我。谢谢

  1. 将hadoop核心文件从hadoop home添加到hbase lib文件夹
  2. 检查群集中的hbase版本。如果存在差异，可能会发生错误。
  3. 使用IP地址而不是localhost
  4. 检查ssh连接。

答案 1 :(得分：0)

如果您在伪模式下运行Hbase，则不需要IP .Loopback工作正常。所以只需将两行“127.0.0.1”...也在您的hbse-site中添加以下2个属性。 xml文件 - 

<property>
  <name>hbase.zookeeper.quorum</name>
  <value>localhost</value>
</property>    
<property>
      <name>hbase.zookeeper.property.clientPort</name>
      <value>2181</value>         
</property>

除此之外，将以下jar添加到您的“HBASE_HOME / lib”目录中 - 来自HADOOP_HOME的“hadoop-core - * - 。jar”和来自HADOOP_HOME / lib目录的“commons-collections-3.2.1.jar”

答案 2 :(得分：0)

不确定这是罪魁祸首，但我确实看到了/ etc / hosts的问题：
您将localhost定义为2个不同的地址。

可能你想要

127.0.0.1   hbase localhost hbase-system
23.21.190.123   hbase.com.com

HTH，
