Subject [jira] [Commented] (HBASE-9165) Improvements to addDependencyJars
Date Thu, 14 Nov 2013 22:07:22 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13822994#comment-13822994

Nick Dimiduk commented on HBASE-9165:

[~lhofhansl] do you want at least a partial backport to 0.94? I think we can leave out the
test refactor if you'd prefer, keep only the new method. This should be helpful for downstream
projects (Pig, Hive). I'd like to include the new method so I can also backport HBASE-8438.

> The way we support adding HBase dependencies to a MapReduce job in {{TableMapReduceUtils#addDependencyJars(job)}}
is a bit monolithic. Advanced users need a way to add HBase and its dependencies to their
job without us snooping around for ouput formats and the like (see PIG-3285). We can also
benefit from a little more code reuse between our {{mapred}} and {{mapreduce}} namespaces.
