Subject [jira] [Created] (HADOOP-7839) Yarn doesn't work if JAVA_HOME isn't set
Date Fri, 18 Nov 2011 15:24:52 GMT
Yarn doesn't work if JAVA_HOME isn't set
----------------------------------------

                 Key: HADOOP-7839
                 URL: https://issues.apache.org/jira/browse/HADOOP-7839
             Project: Hadoop Common
          Issue Type: Bug
          Components: scripts
    Affects Versions: 0.23.0
         Environment: OS/X, JAVA_HOME unset
            Reporter: Steve Loughran
            Priority: Minor


libexec/hadoop-config.sh does reliably work out JAVA_HOME for many platforms. unfortunately,
the yarn scripts don't use it. As such you get told off when you try to run yarn

{code}
$ bin/yarn resourcemanager
Error: JAVA_HOME is not set.

{code}

To make things more interesting, if you set the value in the shell, it still doesn't propagate
down to the scripts
{code}
$ echo $JAVA_HOME

$ source libexec/hadoop-config.sh 
$ echo $JAVA_HOME
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
$ bin/yarn resourcemanager
Error: JAVA_HOME is not set.
$echo $JAVA_HOME
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
{code}
