Subject [jira] [Updated] (HADOOP-7205) automatically determine JAVA_HOME on OS X
Date Wed, 18 May 2011 18:40:47 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-7205?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eli Collins updated HADOOP-7205:
--------------------------------

    Resolution: Fixed
        Status: Resolved  (was: Patch Available)

This dupes HADOOP-6605, which handles java detection via looking for specific, standard java
home's for various versions of Java (which may be used across OS types) rather than use an
os-specific detection method (java_home in OSX). 

Agree with Allen that we avoid OS-specific changes when possible. There are places which care
about host-specific and java-specific issues and these may require some host-specific/java-specific
changes.

> 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.
