Edward J. Yoon commented on HADOOP-2993:
----------------------------------------

That means the setting of the environment variable JAVA_HOME to the root of your Java installation
under your OS.
I don't think it must be fix, but i think we need to explain sth clearly to save confusion.

> Quickstart page (http://hadoop.apache.org/core/docs/current/quickstart.html) specifies
that user should set JAVA_HOME under "1." of "Required Software".  But, it does not specify
where this should be set.  My instinct (as would be the instinct of any un*x user) was to
set this in his/her shell/profie/rcfile.  Please specify that this should be specified in
conf/hadoop-env.sh.  Yes, this is clarified later under "Download", but is easy to miss, especially
since the user will think that he/she had already set JAVA_HOME.
