--------------------------------------
[~aw], could you take a quick look at it? Thanks!

> Key: HADOOP-11983
> URL: https://issues.apache.org/jira/browse/HADOOP-11983
> Project: Hadoop Common
> Issue Type: Bug
> Components: scripts

>
> The behavior of HADOOP_USER_CLASSPATH_FIRST works the opposite of what it
> should do. If it is not set, HADOOP_CLASSPATH is prepended. If set, it is
> appended.
> You can easily try out by doing something like
> {noformat}
> HADOOP_CLASSPATH=/Users/alice/tmp hadoop classpath
> {noformat}
> (HADOOP_CLASSPATH should point to an existing directory)
> I think the if clause in hadoop_add_to_classpath_userpath is reversed.
> This issue seems specific to the trunk.
