我已经在Windows7机器上安装了Hadoop1.x和cygwin，并在.bashrc中设置了home path和bin path，如下所示。

bashrc先生

export JAVA_HOME=/cygdrive/c/java/jdk1.7
export HADOOP_HOME=/cygdrive/c/apache/hadoop
export PATH=$HADOOP_HOME/bin/:$PATH

在命令提示符处执行命令“hadoop version”时，我看到与路径相关的错误消息，如下所示。请指出哪些路径设置不正确。我已经分别在c:/apache/hadoop和c:/java/jdk1.7中安装了hadoop和java。

cygwin命令提示符

$ hadoop version
Warning: $HADOOP_HOME is deprecated.
