Nick Dimiduk commented on HBASE-9112:
-------------------------------------
Inclusion of dependency jars is done in part by inspecting the attributes of
the job and including jars that directly provide those classes. It sounds like
nothing in your job used any class that is directly provided by hbase.jar,
hence the failure. This is a bug.
