Question

当我尝试命令hadoop版本 - 它的工作正常。 hadoop namenode -format命令也正常工作命令start-dfs.sh - 不工作我正进入（状态在[localhost]上启动名称节点 localhost：Bad port＆＃39; localhost＆＃39; localhost：Bad port＆＃39; localhost＆＃39; 启动辅助名称节点[0.0.0.0]

请查看以下配置文件，谢谢。

export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin 
export HADOOP_PID_DIR=/home/.../hadoop-2.7.2/hadoop2_data/hdfs/pid

运行命令./sbin/start-dfs.sh时会出现以下错误。

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'

Answer 1

我面对并按照以下步骤解决了同样的问题，

1）ssh localhost应该得到响应。如果没有，请安装ssh并关闭所有终端，重新启动ssh然后从/ etc / sbin执行start-dfs.sh
2）在hadoop-env.sh中检查HADOOP_OPTS = -Djava.net.preferIPv4Stack = true

Answer 2

有时hadoop会将旧配置文件保存在缓存中，我多次遇到过这类问题。即使您的配置文件对我来说很好，但我怀疑您最初可能错误地将“localhost”作为端口号并尝试启动hdfs。稍后您确实修复了配置并尝试重新启动hdfs，但您的旧配置仍在缓存中。重启服务器应该有帮助。

Answer 3

尝试检查hadoop-env.sh和其他位置的HADOOP_SSH_OPTS。我有同样的问题，原因是我在HADOOP_SSH_OPTS中有一些未完成的参数，如

export HADOOP_SSH_OPTS="-p"

start-dfs.sh -not working - localhost：Bad port＆＃39; localhost＆＃39; （Hadoop 2.7.2）
