在伪分布式模式下无法启动 HBase 会引发"Failed construction RegionServer"

Question

我正在尝试在ubuntu的docker镜像中运行HBase伪分布。

start-hbase.sh后，HMaster和RegionServer不能正常运行

RegionServer和Master日志显示:

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>

这两个配置文件都是从hadoop/etc/hadoop/软链接的我不知道如何根据日志解决这个问题。谢谢你的帮助!

更新:修复了hdfs-site.xml中由majid.

指出的语法错误后

"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)"

您的hdfs-site.xml格式不正确。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>

或去掉dfs.client.failover.proxy.provider.hdfscluster属性，hdfs-site.xml应为

<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>

请在启动HBase前确保格式化namenode。
