Subbu M Iyer commented on HBASE-3909:
-------------------------------------
Attached a first draft for review. It may not address all the reqs mentioned in
this Jira but can be added. (I started with a loose set of requirements and
hope to refine it as we go further)
1. Config will be maintained in ZK.
2. Any runtime config changes survives master/RS crash.
3. Shell support to update config as well as get config value for a config key.
4. Behind a flag and is disabled by default. Can be enabled through a config
change.
5. If enabled, any new config changes will be available instantly with out a
restart.
Please review and let me know your comments. I wanted to get it out here so can
get early comments and work on addressing the same.
