[jira] Created: (HBASE-3203) We can get an order to open a region
while shutting down and it'll hold up regionserver shutdown
We can get an order to open a region while shutting down and it'll hold up regionserver shutdown
------------------------------------------------------------------------------------------------
Key: HBASE-3203
URL: https://issues.apache.org/jira/browse/HBASE-3203
Project: HBase
Issue Type: Bug
Reporter: stack
Fix For: 0.90.0
Starting and stopping clusters I see that an open directive can come in while we are shutting down all the user space regions on a particular regionserver. Regionservers will only shut themselves down after all user space regions have closed. We queue up all the closes at a particular time. If an open comes in while we are in the closing condition, then the regionserver won't go down. The region open needs to be blocked.

Jonathan Gray commented on HBASE-3203:
--------------------------------------
looks fine to me. kind of unfortunate we have new 'stopping' state, but guess we need it because can't just have 'stopped' earlier? makes sense i suppose. anything else we want to reject if closing?
good fix on that completely wrong comment :)
+1 to commit if you've done some testing w/ it

------------------------------
Thanks for the review.
We used to do 'stopping'. Smile.
'Stopping' gets us closer to classic Lifecycle.
I think just needed for this at mo.
