> When migrating from hadoop 1 to hadoop 2, one thing caused our users grief 
> are those non-backward-compatible changes. This JIRA is to fix one of those 
> changes:
>   HADOOP_OPTS is not picked up any more by hadoop command
> With Hadoop 1, HADOOP_OPTS will be picked up by hadoop command. With Hadoop 
> 2, HADOOP_OPTS will be overwritten by the line in conf/hadoop_env.sh :
> export HADOOP_OPTS="-Djava.net.preferIPv4Stack=true"
> We should fix this.
