Subject Re: [jira] Commented: (HADOOP-2993) Specify which JAVA_HOME should be set
Date Fri, 11 Apr 2008 15:02:49 GMT
Let's see the document.

-- Required?

1. java install & set the environment variable JAVA_HOME in your OS.
2. ssh install in your OS.

-- Are you ready?

3. download the hadoop.
4. edit the conf/hadoop-env.sh, set JAVA_HOME in conf/hadoop-env.sh.
5. edit the configuration files.

-- Execution?

6. hadoop FS format & start.

BTW, Jason, Why you recommend the set JAVA_HOME in hadoop-env.sh at first level?

Thanks.

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.
