[jira] [Commented] (HADOOP-11983) HADOOP_USER_CLASSPATH_FIRST works the opposite of what it is supposed to do

    [ https://issues.apache.org/jira/browse/HADOOP-11983?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14546398#comment-14546398 ] 

Sangjin Lee commented on HADOOP-11983:
--------------------------------------

The Windows side seems fine (hadoop-config.cmd).

> 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.
