Subject [jira] [Commented] (HADOOP-6605) Add JAVA_HOME detection to hadoop-config
Date Mon, 13 Jun 2011 17:56:52 GMT

Allen Wittenauer commented on HADOOP-6605:
------------------------------------------

I'll change my vote to 0 for this particular change to add support for OS X.  (I keep meaning
to check Lion but keep forgetting.  Too busy working on other Lion bugs...).  This means we
should change the case statement to a single if test.

> The commands that source hadoop-config.sh currently bail with an error if JAVA_HOME is
not set. Let's detect JAVA_HOME (from a list of locations on various OS types) if JAVA_HOME
is not already set by hadoop-env.sh or the environment. This way users don't have to manually
configure it.
