Nick Dimiduk updated HBASE-8438:
--------------------------------
Attachment: 0001-HBASE-8438-Extend-bin-hbase-to-print-a-minimal-class.patch
Simplified implementation. Since we already manually maintain a list of
mapreduce dependencies over in TableMapReduceUtils, why not use it? This
version builds on addDependencyJars and exposes it on the command line via a
simple utility.
> Extend bin/hbase to print a "minimal classpath" for used by other tools

> 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.
