Jim Kellerman commented on HBASE-614:
-------------------------------------
The window for doing gets while a region is closing is pretty small. Removing
retiringRegions.
> Retiring regions is not used; exploit or remove
> -----------------------------------------------
>
> Key: HBASE-614
> URL: https://issues.apache.org/jira/browse/HBASE-614
> Project: Hadoop HBase
> Issue Type: Improvement
> Affects Versions: 0.2.0, 0.1.2
> Reporter: stack
> Assignee: Jim Kellerman
> Fix For: 0.2.0
>
>
> 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.
