Subject [jira] [Commented] (HBASE-6776) Opened region of disabled/enabling table is not added to online region list
Date Fri, 14 Sep 2012 17:40:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13455973#comment-13455973

Jimmy Xiang commented on HBASE-6776:
------------------------------------

That's a good question.  In rebuilding the user regions, only these regions are added to online
region map: 1. there is a server info in Meta for the region, and 2. the server is online.

Here is the assumption:

For the regions not assigned yet or still in assigning, the meta entry should not have the
server info (assume no region in transition znodes, if there is,
process region in transition will correct the assigning region's state).

For tables not in ENABLING, this is our assumption too. So the question is whether the assumption
correct, right?  I think it is correct.

> For opened region of disabled table, it should be added to online region list, and then
closed.  We should not just ignore them.
> For opened region of enabling table, it should be added to online region list, so that
we don't have to assign it again.  Without adding it to online region list, it could be double
assigned when assign it again later.
