Date Thu, 08 May 2008 20:57:08 GMT

    [ https://issues.apache.org/jira/browse/HBASE-614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12595389#action_12595389

Jim Kellerman commented on HBASE-614:

The window for doing gets while a region is closing is pretty small. Removing retiringRegions.

> There is a little dance around region close where a region first gets moved into the
retiring queue.  The idea, IIRC, was that regions in retiring could serve reads while close
was going about its business.   Meant that region was online that bit longer.
> This feature is not used any more -- regions are added to retiring but gets do not bother
to look in retiring.  We should either remove retiring cocept altogether or else make use
of it again.
