我正在使用 Cygwin 在 Windows 7 64 位上安装 Hadoop。成功格式化 Hadoop 后，我想使用以下命令启动它：start-dfs.sh。但它报告为：

]tarting namenodes on [DATASCIENCES01
: Name or service not knownstname datasciences01
Starting datanodes
]tarting secondary namenodes [0.0.0.0
: Name or service not knownstname 0.0.0.0
]tarting journal nodes [
: Name or service not knownstname

我使用命令： bash -x ./start-dfs.sh 尝试调试：

]tarting namenodes on [DATASCIENCES01
+ hadoop_uservar_su hdfs namenode /cygdrive/c/cygwin64/usr/local/hadoop-3.1.0/bin/hdfs --workers --config /usr/local/hadoop-3.1.0/etc/hadoop --hostnames $'DATASCIENCES01\r' --daemon start namenode

: Name or service not knownstname datasciences01

我看到我的主机名被称为'DATASCIENCES01\r' 而不是'DATASCIENCES01'。

我猜 \r 对应于 Windows 典型的行尾，所以我使用 dos2unix 来转换引用 NameNode 名称的文件 core-site.xml：

<configuration>
<property>
<name>hadoop.tmp.dir</name>
 <value>/opt/hadoop_data</value>
 <description>directory for hadoop data</description>
 </property>
 <property>
 <name>fs.default.name</name>      
 <value>hdfs://DATASCIENCES01:54311</value>
 <description> data to be put on this URI</description>
 </property>
 <property>
 <name>fs.defaultFS</name>
 <value>hdfs://DATASCIENCES01:54311</value>
 <description>Use HDFS as file storage engine</description>
 </property>
 <property>
 <name>dfs.permissions</name>
 <value>false</value>
 </property>
 </configuration>

但它最后并没有改变这个 '\r' 。

我在这个链接上找到了一个类似的主题：

当 Hadoop 2.7 在 Windows 7 64 位上启动时：名称或服务未知名称 localhost

但仍然没有答案。

提前致谢
