好像unix和windows之间的回车符引起了问题. 尝试在shell脚本上运行dos2unix

Seems like carriage return difference between unix and windows is causing the problem . Try running dos2unix on the shell script

转到hadoop bin目录，然后尝试:

Go to the hadoop bin directory and try :

dos2unix.exe hadoop.sh

然后尝试hadoop命令.

And then try the hadoop command .
