Hadoop 主机不运行

大家好，我在主日志中运行HBase时遇到此异常，而HMaster未运行。

我甚至通过注释localhost条目I-e#127.0.0.1 localhost尝试过，但无法运行HMaster。
这是我的hbase-site.xml

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

hbase.cluster.distributed
真的
hbase.rootdir
hdfs://localhost:54310/hbase

这是我的hadoop core-site.xml

如果有人遇到问题，请帮助我
谢谢

如果您在伪模式下运行Hbase，则不需要IP。环回工作正常。因此，只需将两行都设置为“127.0.0.1”…还在hbse-site.xml文件中添加以下两个属性-

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

hbase.zookeeper.quorum
本地服务器
hbase.zookeeper.property.clientPort
2181

除此之外，在“HBASE_HOME/lib”目录中添加以下jar—“hadoop核心-*-.jar”，从hadoop_HOME/lib目录添加“commons-collections-3.2.1.jar”

将hadoop核心文件从hadoop home添加到hbase lib文件夹

检查集群中hbase的版本。如果有差异，则可能是giv错误

使用Ip地址而不是本地主机

检查ssh连接

不确定这是否是罪魁祸首，但我确实看到您的/etc/hosts存在问题：
您将localhost定义为两个不同的地址

也许你想要

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

HTH，

您是在群集环境中运行还是在伪群集（都在一个节点上，并在配置文件中使用

localhost

）中运行？这个问题与此类似（）-他们也错误地将localhost分配给了real IP，而不是环回127.0.0.1是的，我检查了这个问题，但这对我不起作用-无论如何，在mysetup中，所有都在一个节点上，而localhost上如果所有都在一个节点上运行，您能否发布运行

jps

和

netstat-atn | grep LISTEN

命令的输出（在原始问题中发布，而不是在本评论部分发布）您是否在/hbase/conf目录下的regionserver文件中设置了主机名？
