> Assignee: Josh Elser
> Priority: Blocker
> Fix For: 3.0.0, 2.1.0, 2.0.2, 2.2.0

> Next problem we've run into after HBASE-20752 and HBASE-20708
> After a rolling restart of a cluster, we'll see situations where a collection
> of regions will simply not be assigned out to the RS. I was able to reproduce
> this my mimic the restart patterns our tests do internally (ignore whether
> this is the best way to restart nodes for now :)). The general pattern is
> this:
> {code:java}
> for rs in regionservers:
> stop(server, rs, RS)
> for master in masters:
> stop(server, master, MASTER)
> sleep(15)
> for master in masters:
> start(server, master, MASTER)
> for rs in regionservers:
> start(server, rs, RS){code}
> Looking at meta, we can see why the Master is ignoring some regions:
> {noformat}

> The region is marked as {{OPEN}}. The master doesn't know any better.
> However, the interesting bit is that {{info:server}} and {{info:sn}} are
> inconsistent (which, according to the javadoc should not be possible for an
> {{OPEN}} region).{{}}
> This doesn't happen every time, but I caught it yesterday on the 2nd or 3rd
> attempt, so I'm hopeful it's not a bear to repro.
