Paul Han commented on HADOOP-9625:
----------------------------------

Thanks Arpit for merging it to trunk!

Is it possible for you to apply it to branch 2x as well? That way the patch is available when
we sync our build with 2.0.x releases.

> 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.
