Subject [jira] [Resolved] (HBASE-11843) MapReduce classes shouldn't be in hbase-server
Date Thu, 21 Sep 2017 05:03:00 GMT

     [ https://issues.apache.org/jira/browse/HBASE-11843?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack resolved HBASE-11843.
---------------------------
    Resolution: Duplicate

Resolving as duplicate of HBASE-18640 "Move mapreduce out of hbase-server into separate module"
though HBASE-18640 came later.

This issue had great subtasks that I moved out as standalone. They are linked here.

> I'm opening this to continue the discussion I started a while back: http://mail-archives.apache.org/mod_mbox/hbase-user/201405.mbox/%3CCAMUu0w_XooxeG779rRFjTuRAU+UxeAvuNzxKw9dxFO-gh5yVUw@mail.gmail.com%3E.
> To summarize, I think the MapReduce classes used by clients (like TableMapper, TableReducer,
etc) don't belong in hbase-server.  This forces the user to pull in a rather large artifact
for a relatively small number of classes.  These should either be put in hbase-client, or
possibly an artifact of their own (like the hbase-mapreduce idea Enis suggested).
