Subject [jira] [Created] (BIGTOP-25) Standardize JAVA_HOME detection
Date Fri, 19 Aug 2011 00:22:27 GMT
Standardize JAVA_HOME detection
-------------------------------

                 Key: BIGTOP-25
                 URL: https://issues.apache.org/jira/browse/BIGTOP-25
             Project: Bigtop
          Issue Type: Bug
            Reporter: Roman Shaposhnik
            Assignee: Roman Shaposhnik
            Priority: Minor


The Hadoop packages go through some effort (see /usr/lib/hadoop-0.20/bin/hadoop-config.sh)
to guess at a good JVM to use if JAVA_HOME isn't set. For example, if both OpenJDK and Oracle
JDK are installed, hadoop-config.sh will choose Oracle every time. Other packages that Bigtop
integrates, don't follow the same practice (ZK, Pig, etc.). It would be nice to have this
common code shared.
