hdfs-core.xml配置如下

Answer 1

不知道你是怎么配的 应该是配置hdfs-site.xml文件
下面这些内容你没有配置

#指定journal地址和端口号
<property>
    <name>dfs.namenode.shared.edits.dir</name>
    <value>qjournal://master:8485;slave1:8485;slave2;8485/ns</value>
</property>
#指定namenode元数据在journalnode上的存放位置
<property>
    <name>dfs.journalnode.edits.dir</name>
    <value>/usr/local/src/hadoop/journal</value>
</property>
#开启HA自动切换
<property>
    <name>dfs.ha.automatic-failover.enabled</name>
    <value>true</value>
</property>
#设置失败自动切换方式
<property>
    <name>dfs.client.failover.proxy.provider.ns</name>
<value>org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider</value>
</property>
#设置隔离机制 ssh会因为无权限访问导致自动切换失败,此时直接使用shell
<property>
<name>dfs.ha.fencing.methods</name>
<value>shell(/bin/true)</value>
</property>
#设置使用ssh隔离时需要ssh免密登录
<property>
<name>dfs.ha.fencing.ssh.private-key-files</name>
<value/root/.ssh/id_rsa></value>
</property>

报错应该是指这个配置 当然 这是我自己的主机上的配置 具体端口 主机名需要你自己修改

<property>
    <name>dfs.namenode.shared.edits.dir</name>
    <value>qjournal://master:8485;slave1:8485;slave2;8485/ns</value>
</property>
