我正在使用Cygwin在7位64位窗口上安装Hadoop。成功格式化Hadoop之后，我想使用以下命令启动它：start-dfs.sh。但报告为：
]tarting namenodes on [DATASCIENCES01

Starting datanodes
]tarting secondary namenodes [0.0.0.0

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' 代替“ DATASCIENCES01” 。
我想\ 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>
但是最后它不会更改此'\ r'。
我在此链接上找到了类似的主题：
When Hadoop 2.7 start on windows 7 64 bits: Name or service not knownstname localhost
但是仍然没有答案。
预先感谢
