Subject [jira] [Commented] (HBASE-4991) Provide capability to delete named region
Date Fri, 24 Feb 2012 01:05:48 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4991?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13215288#comment-13215288

Mubarak Seyed commented on HBASE-4991:

The log of intent would list the steps to be done
Is it Okay to do the above in another JIRA ?
As a prereq for this issue? Yes.
Please correct me if i am wrong, if we introduce prereq then we need to design (as you asked)
the intent part (a bare mini language..) and actual delete_region implementation needs to
interpret (as Ted mentioned) the steps from intent (from ZK). Do we need to design the intent
part (and steps of an operation) as a generic framework for all the master-coordinated tasks?

I thought we are only changing the API (with multiple region support) and focussing more on
refactoring with good test/stress-test in this JIRA.

Can we address intent/actions part out of scope of this JIRA?
