我正在用cygwin在window7 64位上安装hadoop。在成功格式化hadoop之后，我希望使用命令start-dfs.sh启动它。但报告称：

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，因此我使用dos2unix来转换文件core-site.xml，其中引用了namenode名称：

<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>

但它不会改变结尾的'\r'。
我在这个链接上发现了一个类似的主题：
当hadoop2.7在windows7上启动时64位：name or service not knownstname localhost
但仍然没有答案。
提前谢谢
