Subject [jira] [Created] (HADOOP-11033) /bin/hdfs script ignores JAVA_HOME
Date Fri, 29 Aug 2014 21:53:53 GMT
Lei (Eddy) Xu created HADOOP-11033:
--------------------------------------

             Summary: /bin/hdfs script ignores JAVA_HOME
                 Key: HADOOP-11033
                 URL: https://issues.apache.org/jira/browse/HADOOP-11033
             Project: Hadoop Common
          Issue Type: Bug
          Components: scripts
    Affects Versions: 3.0.0
         Environment: Mac OSX with both JDK_1.7.0_67 and JDK_1.8.0_20 installed.
            Reporter: Lei (Eddy) Xu


Running {{start-dfs.sh}} script should pick the java specified by JAVA_HOME which is defined
in my {{~/.zshrc}} and {{~/.bashrc}}.  

My JAVA_HOME is
{noformat}
 $ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home
{noformat}

However, when I start a local cluster using {{start-dfs.sh}}, it reports

{noformat}
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk/Contents/Home
2014-08-29 14:48:20,767 INFO  [main] namenode.NameNode (StringUtils.java:startupShutdownMessage(633))
- STARTUP_MSG:
.....

STARTUP_MSG:   java = 1.8.0_20
{noformat}

It is expected to use JDK 7 instead. This bug only occurs on trunk, but not branch-2.
