Sergey Shelukhin commented on HBASE-5487: ----------------------------------------- The doc hasn't been out for long; just clarifying - anyone interested in providing feedback for part 1? It'd be really nice to start working out implementation details in part 2 with some confidence, and/or writing code. Should I assume lack of interest or silent agreement to rewrite according to part 1? > 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, 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 -- This message was sent by Atlassian JIRA (v6.1#6144)
