If java is installed in c:\Program Files\Java\, it is headache to make Hadoop/Hive works. Hive reports an error like this:

/workplace/apps/hadoop-0.20.2-cdh3u1/bin/hadoop: line 300: /cygdrive/c/Program:
No such file or directory

Apparently the space in JAVA_HOME doesn't work.

I tried several solutions on the Internet, but none of them works. For example,

export JAVA_HOME=/cygdrive/c/Program\ Files/Java/jdk1.6.0_25
export JAVA_HOME=/cygdrive/c/"Program Files"/Java/jdk1.6.0_25

Here is how I solve this problem: create a soft link like this

ln -s /cygdrive/c/Program\ Files/Java/jdk1.6.0_25 /usr/java/default

and set JAVA_HOME in ${HADOOP_HOME}/conf/hadoop-env.sh like this

export JAVA_HOME=/usr/java/default

  3. It doesn't work for me. I issue command in cygwin installed on Window XP SP3. I got error.
    $ ln -s /cygdrive/c/Program\ Files/Java/jdk1.7.0_25 /usr/java/default
    ln: failed to create symbolic link `/usr/java/default': No such file or directory

    Do I have to create folder /usr/java/default first?

    1. Yes. Make sure the directory '/usr/java' exists, if not, create it, then ln will create /usr/java/default.
