我把jdk放在“e:/cygwin/jdk7”中，所以我更新了 JAVA_HOME 在环境和hadoop-env.sh中。但是当我第一次运行./hdfs namenode-format时，我得到了以下结果：

$ ./hdfs namenode -format
    E:/cygwin/hadoop-2.2.0/etc/hadoop/hadoop-env.sh: line 18: $'\r': command not found

    E:/cygwin/hadoop-2.2.0/etc/hadoop/hadoop-env.sh: line 20: $'\r': command not found

    E:/cygwin/hadoop-2.2.0/etc/hadoop/hadoop-env.sh: line 25: $'\r': command not found

    E:/cygwin/hadoop-2.2.0/etc/hadoop/hadoop-env.sh: line 32: $'\r': command not found

    E:/cygwin/hadoop-2.2.0/etc/hadoop/hadoop-env.sh: line 34: $'\r': command not found

    E:/cygwin/hadoop-2.2.0/etc/hadoop/hadoop-env.sh: line 36: syntax error near unexpected token `$'do\r''':/cygwin/hadoop-2.2.0/etc/hadoop/hadoop-env.sh: line 36: `for f in $HADOOP_HOME/contrib/capacity-scheduler/*.jar; do/bin/java: No such file or directory
   /bin/java: cannot execute: No such file or directory

我更改了core site.xml、hdfs site.xml、mapred site.xml、yarn-site.xml等数百次，但仍然无法正常工作
如果有人给我任何建议，我将不胜感激！
