Looks good to merge.
Like Robert said, the `HADOOP_CLASSPATH` is used to add third party
libraries. From `hadoop-env.sh`:
# Extra Java CLASSPATH elements. Automatically insert
capacity-scheduler.
for f in $HADOOP_HOME/contrib/capacity-scheduler/*.jar; do
if [ "$HADOOP_CLASSPATH" ]; then
export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$f
else
export HADOOP_CLASSPATH=$f
fi
done
> Add HADOOP_CLASSPATH to start scripts

>
> With the Hadoop file system wrapper, its important to have access to the
> hadoop filesystem classes.
> The HADOOP_CLASSPATH seems to be a standard environment variable used by
> Hadoop for such libraries.
> Deployments like Google Compute Cloud set this variable containing the
> "Google Cloud Storage Hadoop Wrapper". So if users want to use the Cloud
> Storage in an non-yarn environment, we need to address this issue.
