Lars Hofhansl commented on HBASE-8438:
--------------------------------------

Maybe I am dense today.

When I call this tool with just {{bin/hbase mapredcp}}, it would fail. Right?
Should it not print out hbase's additional default dependencies?

> 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.
