Nick Dimiduk updated HBASE-8438:
--------------------------------
Attachment: HBASE-8438-0.94.00.patch
Here's a backport for 0.94. I'll need to update it as well once HBASE-9165
makes it in, that way the hadoop jar will be excluded. Here's output:

> For tools like pig and hive, blindly appending the full output of `bin/hbase
> classpath` to their own CLASSPATH is excessive. They already build CLASSPATH
> entries for hadoop. All they need from us is the delta entries, the
> dependencies we require w/o hadoop and all of it's transitive deps. This is
> also a kindness for Windows, where there's a shorter limit on the length of
> commandline arguments.
> See also HIVE-2055 for additional discussion.
