Okay so that was incorrectly stated in the Javadoc - if you read

I disagree with the proposed changes.
Most folks are missing the point of limited private.
The Jira (HADOOP-5073) that created this classification gives a very
detailed explanation of the motivation and purpose of the
Unfortunately most of the explanation in Jira were not copied to the
Javadoc. My mistake here.
I will file a jira to copy the classification documentation from the
Jira to a Javadoc.
BTW the the javadoc is incorrect
> Private means "Intended for use only within

The definition in the Jira (Hadoop-5073) explains that private means
project private. It is private to HDFS or private to MR etc. Private
does not mean private to Hadoop - otherwise MR can use any internal
private class inside HDFS. We don't want that.
When we did the actual annotation tags the words project-private was
simplified to private since folks felt it was too verbose.
The Jira states:
the interface is for internal use within the project and should not be
used by applications. It is subject to change at anytime without
notice. Most interfaces of a project are project private.
My mistake for not checking the actual javadoc carefully when Jacob's
annotations patch was committed.
I will file a jira to copy the document from the Jira to the Javadoc.
I will post a longer email explaining my position and my -1 more
clearly after I have had a chance to read all the emails carefully.
