Enis Soztutar commented on HBASE-9514:
--------------------------------------
The patch at RB (v4) looks mostly ok to me, although I must admit that I do not
get the full details of AM internals. I am running the ITBL to see whether it
fixes that problem.
> Prevent region from assigning before log splitting is done

> 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.
