Eric Yang commented on CHUKWA-302:
----------------------------------
The current patch will fall back to CHUKWA_HOME/hadoopjar for the hadoop jar
file. Since the hadoopjar in CHUKWA_HOME is package and supplied by chukwa at
build time, it should always be compatible. If it's standalone web server, it
is unlikely user would have HADOOP_HOME or HADOOP_JAR defined.
In the remote case which the user has HADOOP_HOME defined in chukwa-env.shand
cause the agent to break due to version incompatibility. We could add some
extra wording in chukwa-env.sh to prevent this case from happening.

> agent.sh is hard coded with HADOOP_20_JAR. However, this may not reflect the
> correct running version of the hadoop library. agent.sh should obey
> HADOOP_JAR variable.
