Nick Dimiduk commented on HBASE-5487:
-------------------------------------
I cannot comment on a WAL implementation vs this FATE stuff. Before I left on
holiday, I had an FateManager integrated into HMaster and mostly ported over
CreateTable as a FATE repo. The next task is to extract a Fate client and push
it out to the client HBaseAdmin. I can make a priority to clean up my pending
code and post another review, particularly if someone else is chomping to pick
up the FATE PoC.
Please advise.
> 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: Nick Dimiduk
>
> 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
