Subject [jira] [Updated] (HADOOP-6605) Add JAVA_HOME detection to hadoop-config
Date Wed, 18 May 2011 17:54:47 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6605?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eli Collins updated HADOOP-6605:
--------------------------------

    Attachment: hadoop-6605-1.patch

Patch attached. Implements the behavior in the (updated) description. 

It detects Java for a number of different version of java (Linux platform default, Sun Java)on
a couple different host types (Linux, Mac, tar install). It looks for Sun Java first since
Hadoop currently requires Sun java. This list can be updated for other host types (eg add
/usr/local for Solaris).

> 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.
