hadoop - 在伪分布式模式下启动 HBase 失败抛出“Failed construction RegionServer”

Question

我正在尝试在 ubuntu 的 docker 映像中运行 HBase 伪分布。

start-hbase.sh 后，HMaster 和 RegionServer 无法正常运行。

RegionServer 和 Master 日志都显示：

ERROR [main] regionserver.HRegionServer: Failed construction RegionServer

jps 显示：

31168 HQuorumPeer
14801 NodeManager
2049 Jps
12435 SecondaryNameNode
12105 NameNode
14699 ResourceManager
14141 DataNode

core-site.xml 是：

<configuration>
<property>
<name>hadoop.tmp.dir</name>
<value>/bigdata/hadoop/tmp</value>
</property>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>

hdfs-site.xml 显示：

<configuration>
   <property>
<name>dfs.replication</name>
<value>1</value>
</property>

<property>
<name>dfs.namenode.name.dir</name>
<value>/usr/local/hadoop/yarn_data/hdfs/namenode</value>
</property>

<property>
<name>dfs.datanode.data.dir</name>
<value>/usr/local/hadoop/yarn_data/hdfs/datanode</value>
</property>

<property>
<name>dfs.namenode.http-address</name>
<value>localhost:50070</value>
</property>
<configuration>

    <property>
        <name>dfs.client.failover.proxy.provider.hdfscluster</name>
        <value>org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider</value>
    </property>
</configuration>
</configuration>

这两个配置文件都从 hadoop/etc/hadoop/ 软链接我不知道如何根据日志解决此问题。谢谢您的帮助！

更新：修复了 majid 指出的 hdfs-site.xml 中的语法错误后。

"ERROR [main] regionserver.HRegionServer: Failed construction RegionServer
java.lang.IllegalArgumentException: java.net.UnknownHostException: hdfs
        at org.apache.hadoop.security.SecurityUtil.buildTokenService(SecurityUtil.java:448)
        at org.apache.hadoop.hdfs.NameNodeProxiesClient.createProxyWithClientProtocol(NameNodeProxiesClient.java:139)"

你hdfs-site.xml的格式不正确。它应该是：

<configuration>
 <property>
    <name>dfs.nameservices</name>
    <value>hdfscluster</value>
 </property>

<property>
  <name>dfs.replication</name>
  <value>1</value>
</property>

<property>
<name>dfs.namenode.name.dir</name>
<value>/usr/local/hadoop/yarn_data/hdfs/namenode</value>
</property>

<property>
<name>dfs.datanode.data.dir</name>
<value>/usr/local/hadoop/yarn_data/hdfs/datanode</value>
</property>

<property>
<name>dfs.namenode.http-address</name>
<value>localhost:50070</value>
</property>
<property>
  <name>dfs.client.failover.proxy.provider.hdfscluster</name>
  <value>org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider</value>
</property>
</configuration>

或删除dfs.client.failover.proxy.provider.hdfscluster财产，hdfs-site.xml应该是

<configuration>
   <property>
<name>dfs.replication</name>
<value>1</value>
</property>

<property>
<name>dfs.namenode.name.dir</name>
<value>/usr/local/hadoop/yarn_data/hdfs/namenode</value>
</property>

<property>
<name>dfs.datanode.data.dir</name>
<value>/usr/local/hadoop/yarn_data/hdfs/datanode</value>
</property>

<property>
<name>dfs.namenode.http-address</name>
<value>localhost:50070</value>
</property>
</configuration>

确保在启动 HBase 之前格式化 namenode。
