Arun C Murthy commented on HADOOP-2993:
---------------------------------------
Jason, I understand where you are coming from.
Would it be more clear if we just had:
{noformat}
Required Software
1. JavaTM 1.5.x, preferably from Sun, must be installed.
{noformat}
and then this section (later in quickstart.html) is sufficient:
{noformat}
Download
First, you need to get a Hadoop distribution: download a recent stable release and unpack it.
Once done, in the distribution edit the file conf/hadoop-env.sh to define at least JAVA_HOME.
{noformat}
Basically I'm proposing we remove the confusing reference from the 'Required Software' section.
Thoughts?
Specify which JAVA_HOME should be set

Key: HADOOP-2993
URL:
https://issues.apache.org/jira/browse/HADOOP-2993Project: Hadoop Core
Issue Type: Improvement
Components: documentation
Affects Versions: site
Environment: irrelevant---issue w/ web documentation
Reporter: Jason Rennie
Assignee: Edward J. Yoon
Attachments: 2993.patch
Original Estimate: 0.08h
Remaining Estimate: 0.08h
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.
