Miklos Szegedi commented on MAPREDUCE-6989:
-------------------------------------------
One more thing, this tool should run only once per upgrade to update the
framework only. Individual tasks can still specify their own jars and use the
shared cache for those.

> The proposal is to create a tool that collects all available jars in the
> Hadoop classpath and adds them to a single tarball file. It then uploads the
> resulting archive to an HDFS directory. This saves the cluster administrator
> from having to set this up manually for Distributed Cache Deploy.
