从cygwin命令提示符执行“hadoop version”时显示的路径不正确

Question

我在Windows 7机器上安装了Hadoop 1.x和Cygwin，并在.bashrc中设置了主路径和bin路径，如下所示。

的.bashrc

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

执行命令＆＃34; hadoop版本＆＃34;在命令提示符下，我看到与路径相关的错误消息，如下所示。请指导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.

/cygdrive/c/apache/hadoop/bin/hadoop: line 350: /cygdrive/c/java/jdk1.7/bin/bin/java: No such file or directory
cygwin warning:
  MS-DOS style path detected: C:\apache\hadoop\/build/native
  Preferred POSIX equivalent is: /cygdrive/c/apache/hadoop/build/native
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.
  Consult the user's guide for more details about POSIX paths:

Answer 1

将hadoop-env.sh中的Java主路径从/cygdrive/c/java/jdk1.7/bin更改为/cygdrive/c/java/jdk1.7后，我能够解决问题
