Nicolas Liochon commented on HBASE-5487:
----------------------------------------

+1 for Enis' requirements list :-).
I tend to think that AM and meta should be collocated.

> Need a framework to execute master-coordinated tasks in a fault-tolerant manner. 
> Master-coordinated tasks such as online-scheme change and delete-range (deleting region(s)
based on start/end key) can make use of this framework.
> The advantages of framework are
> 1. Eliminate repeated code in Master, ZooKeeper tracker and Region-server for master-coordinated
tasks
> 2. Ability to abstract the common functions across Master -> ZK and RS -> ZK
> 3. Easy to plugin new master-coordinated tasks without adding code to core components
