Jerome Boulon commented on CHUKWA-297:
--------------------------------------
>> by using environment controlled class path
If HADOOP_HOME and HADOOP_CONF_DIR are correctly set in build.properties then
you should have the right classpath for hadoop jars???
>From chukwa-config.sh:
if [ -z ${HADOOP_JAR} ]; then
if [ -z ${HADOOP_HOME} ]; then
export HADOOP_HOME=../../..
fi
if [ -d ${HADOOP_HOME} ]; then
export HADOOP_JAR=`ls ${HADOOP_HOME}/hadoop-*-core.jar`
if [ -z ${HADOOP_JAR} ]; then
echo "Please make sure hadoop-*-core.jar exists in ${HADOOP_HOME}"
exit -1
fi
else
if [ -d ${CHUKWA_HOME}/hadoopjars ]; then
echo "WARNING: neither HADOOP_HOME nor HADOOP_JAR is set we we are
reverting to defaults in $CHUKWA_HOME/hadoopjars dir"
export HADOOP_JAR=`ls ${CHUKWA_HOME}/hadoopjars/hadoop-*-core.jar`
else
echo "Please make sure hadoop-*-core.jar exists in
${CHUKWA_HOME}/hadoopjars"
exit -1

> 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.
