Jakob Homan commented on HADOOP-6541:
-------------------------------------
I really like this idea and jline would be a good way to do it, but I'm not
sure a separate contrib module is the way to go. FsShell is definitely due for
a refactoring/improvement, and this might be the opportunity to do it. Aaron's
comments re: speed issues are correct. In addition, there's no getting around
that our current command line tools are rather clunky and could be improved
within a shell context. This is a pain point for our users, both new and
experienced. But since this is true, why not go all the way and improve
FsShell with these features rather than creating a contrib module that has some
code duplication and will have to be maintained separately?
