Enis Soztutar commented on HBASE-9514:
--------------------------------------
Thanks Jimmy. The test I ran failed at the generator this time, because of two
regions was stuck on FAILED_CLOSE:

This is definitely related to the latest patch. I can dig a bit more.
> Prevent region from assigning before log splitting is done

> Reporter: Jimmy Xiang

> If a region is assigned before log splitting is done by the server shutdown
> handler, the edits belonging to this region in the hlogs of the dead server
> will be lost.
> Generally this is not an issue if users don't assign/unassign a region from
> hbase shell or via hbase admin. These commands are marked for experts only in
> the hbase shell help too. However, chaos monkey doesn't care.
> If we can prevent from assigning such regions in a bad time, it would make
> things a little safer.
