Arun C Murthy commented on HADOOP-6910:
---------------------------------------

Not clear if Commons Config is a good fit:
# It doesn't seem to have have support for 'final' parameters which is critical for the server-side, we need to at least open a feature request there.
# Commons config doesn't seem to have support for context sensitive configs e.g. getMemory("foo", 1KB) - another feature reqeust. I believe Philip had a good proposal, I can't seem to find the jira.
# Commons config doesnt' seem to have support for min/max values per config knob- another feature request. Again, Philip's jira covered if I remember right.

None of these are blockers but for support for 'final' parameters, but we need to be careful we make the switch.

> Replace or merge Configuration with Jakarta Commons Configuration
