Question

我正在尝试在Macbook上设置hadoop 2.7。我正在遵循here中详细介绍的所有步骤。另外，请在下面找到我的配置文件。

.bashrc

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_261.jdk/Contents/Home

export HADOOP_OPTS=-Djava.net.preferIPv4Stack=true

alias hstart="/Users/praveen/Documents/Dev/hadoop/hadoop-2.7.2/sbin/start-all.sh"
alias hstop="/Users/praveen/Documents/Dev/hadoop/hadoop-2.7.2/sbin/stop-all.sh"

        <value>mapreduce_shuffle</value>
    </property>

    </property>
</configuration>

我搜索了解决方案，并使用以下详细信息更新了hadoop-env.sh，这些详细信息仅在stackoverlow的其他几篇文章中提出。

hadoop-env.sh

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_261.jdk/Contents/Home
export HADOOP_OPTS=-Djava.net.preferIPv4Stack=true
export HADOOP_SSH_OPTS="-p"

此外，我也设置了ssh键。 ssh localhost工作正常。 hdfs format命令成功完成，并显示以下输出

hdfs namenode -format

20/08/14 23:23:54 INFO common.Storage: Storage directory /usr/local/Cellar/hadoop/hdfs/tmp/dfs/name has been successfully formatted.
20/08/14 23:23:54 INFO namenode.NNStorageRetentionManager: Going to retain 1 images with txid >= 0
20/08/14 23:23:54 INFO util.ExitUtil: Exiting with status 0
20/08/14 23:23:54 INFO namenode.NameNode: SHUTDOWN_MSG: 
/************************************************************
SHUTDOWN_MSG: Shutting down NameNode at Praveen.local/192.168.29.199
************************************************************/

但是，在那之后，当我尝试启动dfs时，它每次都会失败，并显示以下消息。

sbin/start-dfs.sh
20/08/14 23:24:34 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Starting namenodes on [localhost]
localhost: Bad port 'localhost'
localhost: Bad port 'localhost'
Starting secondary namenodes [0.0.0.0]
0.0.0.0: Bad port '0.0.0.0'
20/08/14 23:24:40 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

我每次都会收到此错误-localhost: Bad port 'localhost'和0.0.0.0: Bad port '0.0.0.0'。我已经尝试了所有不同的解决方案，这在我可以获得的所有帖子中都有详细说明。我什至重新启动了系统几次，甚至清除了缓存的设置（如果有的话）。不幸的是，我无法解决此问题。

任何帮助解决此问题并启动namenode和datanode的帮助/建议都将非常有帮助。
