我已经在macos系统上安装了hadoop，但未能连接到hdfs。配置文件如下：
core-site.xml：

<configuration>  
<property>
     <name>hadoop.tmp.dir</name>
     <value>/usr/local/Cellar/hadoop/hdfs/tmp</value>
     <description>A base for other temporary directories.</description>
  </property>
  <property>
     <name>fs.default.name</name>                                     
     <value>hdfs://localhost:9000</value>                             
  </property>
</configuration>

mapred-site.xml:

<configuration>
<property>
<name>mapred.job.tracker</name>
<value>localhost:9010</value>
</property>
</configuration>

hdfs-site.xml：

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

我跑了 /usr/local/opt/hadoop/sbin/start-dfs.sh;/usr/local/opt/hadoop/sbin/start-yarn.sh 启动hadoop。启动后，我得到下面的错误。我做错什么了吗？

$ hadoop fs -ls
