[jira] [Commented] (HADOOP-7205) automatically determine JAVA_HOME
on OS X
[ https://issues.apache.org/jira/browse/HADOOP-7205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13009788#comment-13009788 ]
Allen Wittenauer commented on HADOOP-7205:
------------------------------------------
-1
a) We've been avoiding OS-specific changes in the shells for a very long time, including one to autodetect Java on various Linux distributions. I see no reason to reverse this now. I've said it before and I'll say it again: stuff like this should really go into an installer that modifies hadoop-env.sh, not part of the base executable.
b) Given that Java is moving from Apple controlled to Oracle controlled on OS X, there is a very good chance this command will disappear in a future release.

> OS X provides a java_home command that will return the user's selected jvm. The hadoop-env.sh should use this command if JAVA_HOME is not set.
