Chris Douglas updated HADOOP-2843:
----------------------------------
Attachment: 2843.patch
This probably belongs in 0.16.1. Unless these are made public, one has no
reasonable way to add new leaf nodes. Originally assumed to be a light
restriction, users of this package have demonstrated that it is a immodest
obstacle to the problems they hope to apply it to.
> mapred.join access control is overly restrictive

> Currently, most of the o.a.h.mapred.join code is package-private, permitting
> meaningful extension only from MultiFilterRecordReader and JoinRecordReader.
> It should be opened up to permit users to add operations not strictly
> descending from the existing hierarchy.
