错误原因

类名错误

解决方法

hdfs-site.xml内

<!-- 配置namenode失败自动切换的实现方式 --><property><name>dfs.client.failover.proxy.provider.mycluster</name><value>org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProvider</value></property>

修改为

<!-- 配置namenode失败自动切换的实现方式 --><property><name>dfs.client.failover.proxy.provider.mycluster</name><value>org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider</value></property>
