-----------------------------------------
We need some convention for inline responses in the mailing list (or tell me if
there's one) :)
> Generic framework for Master-coordinated tasks
> ----------------------------------------------

> Key: HBASE-5487
> URL: https://issues.apache.org/jira/browse/HBASE-5487
> Project: HBase
> Issue Type: New Feature
> Components: master, regionserver, Zookeeper
> Affects Versions: 0.94.0
> Reporter: Mubarak Seyed
> Assignee: Sergey Shelukhin
> Priority: Critical
> Attachments: Entity management in Master - part 1.pdf,
> hbckMasterV2-long.pdf, Region management in Master5.docx, Region management
> in Master.pdf
>
>
> 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
