Subject [jira] Created: (CHUKWA-297) Unbundling hadoop jar file
Date Tue, 16 Jun 2009 00:58:07 GMT
Unbundling hadoop jar file
--------------------------

                 Key: CHUKWA-297
                 URL: https://issues.apache.org/jira/browse/CHUKWA-297
             Project: Hadoop Chukwa
          Issue Type: Bug
          Components: build and test code
    Affects Versions: 0.1.2, 0.2.0
         Environment: Redhat EL 5.1, Java 6
            Reporter: Eric Yang
            Assignee: Eric Yang
            Priority: Blocker


During the deployment, the most frequently issue is hadoop version mismatch.  When this happens,
the hadoop jar files needs to be copied to both CHUKWA_HOME/hadoopjars, and hicc/WEB-INF/lib.
 We should be able to work around both issues by using environment controlled class path.
 For build time, the HADOOP_JAR variable could be overwritten by default.properties and build.properties
to source in hadoop jar file.  If this is this sounds good, then I vote for removing the hadoop-*.jar
file from hadoopjars directory in the upcoming release.  This change would reduce the amount
of hand tweak on the deployment system.  Suggestion and feedback are welcome.
