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.
